Some mpeg versions use LSF (low sampling frequency) when encoding
low sample rates which changes a bit how the side info is layed out.
Also skip trying to separate data and other_data as after reading up
a bit on how main data begin and bit reservoir works i think it was done
incorrectly. To know the real audio data length i think you need to decode
the huffman tables. Instead just have a "audio_data" field which are the
bits with audo data for current and possibly following frames.
Doing it thru a propery in the decode fn feels a bit hidden and will
also not get set on failed decoding.
Now array is not range sorted, logic is you care about index number and ordering.
Struct is range sorted as you will prefer to fields by name.
Move registry to interp and add support for functions and filesystems.
This will be used later for allow formats to add own functions and fq code.
Add gojqextra function helpers to have more comfortable API to add functions.
Takes care of argument type casting and JQValue:s and some more things.
Refactor interp package to use new function helper and registry. Probably
fixes a bunch of JQValue bugs and other type errors.
Refactor out some mpeg nal things to mpeg format.
Refactor interp jq code into display.q and init.jq.
Remove undocumented aes_ctr funciton, was a test. Hopefully will add more crypto things laster.
Decode API design is that Try* returns error non-Try panics.
Also rename Must* as they should panic and introduce some new Try* functions
that were missing.
Each trun has it's own data offset, before the last offset was wrongly used
for all truns. Could also cause sample ranges to be beyond EOF.
tenc: Decode default constant iv
Fixes#292
Add toxml/fromxml for XML encoding, mighe be lossy on ordering
fromxml has {seq:bool} to add #seq attributes to improve ordering
toxml has {indent:number} to choose space indent depth
Add tojson, same as in jq but also has {indent:number} options
Add toyaml/fromyaml for YAML
Add totoml/fromtoml for TOML
Add tojq/fromjq for jq-flavored JSON (optional quotes for keys, comments and trailing commas support)
Add tocsv/fromcsv for CSV
formcvs takes {comma:string, comment:string} for custom separtor and comment character
Rename/split hex into tohex/fromhex
Rename/split base64 into tobase64/frombase64
tobase64/frombase64 takes {encoding:string} option for base64 flavour (std, url, rawstd, rawurl)
Add to/from<format> urlpath, urlquery, url, xmlentities, base64, hex
Add to<hash> md4, md5, sha1, sha256, sha512, sha3_224, sha3_256, sha3_384, sha3_512
Add to/from<encoding> iso8859-1, utf8, utf16, utf16le, utf16be
PSSH decoding probably got broken in some refactoring. system id is 16 bytes,
also scalar mapper should use cloned reader to not affect reader which in the case
broke reading system id bytes.
Add test with playread and widevine pssh boxes
Related to #282
Rename s/interface{}/any/g
Preparation for using generics in decode API and native jq funcations etc
Remove some unused linter ignores as linter has been fixed
Will produce one field per sample which is a bit too much.
Maybe in some future fq can have smart array types that could handle this better.
Also add data_format per track to make it easier to understand things.
Fragmened mp4s can have no tkhd box or tkhd box with a track_id that does not match
any tfhd box track_id. Make is possible to see samples for these fragmented tracks
ny adding tracks for unseen track_ids.
Also add id field for tracks.
Some formats might want to control child order
mp4: Keep tracks in track id order
dns: Keep label component order
elf: Keep seciton order
macho: Keep command and section order
interp: Refactor format help and also include options
interp: Add -o name=@path to load file content as value (not documented yet, might change)
interp,decode: Expose decode out value as _out (might change)
interp: Refactor foramts.jq into format_{decode,func,include}.jq
interp: Refactor torepr into _format_func for generic format function overloading
interp: Refactor -o options parsing to be more generic and collect unknowns options to be used as format options
decode of decode alises
func for format overloaded functions
include for format specific jq functions (also _help, torepr etc)
flac_frame: Add bits_per_sample option
mp3: Add max_unique_header_config and max_sync_seek options
mp4: Add decode_samples and allow_truncate options
avc_au: Has length_size option
hevc_au: Has length_size option
aac_frame: Has object_typee option
doc: Rewrite format doc generation, less hack more jq
mp3: Remove one level of struct for granales
dump: Makes it a bit easier to understand array of arrays/structs.
avro_ocf: Rename ocf.go -> avro_ocr.go to have same name of source file as format
pcap,pcapng: Rename tcp flow struct to tcp_connection, makes more sense i think
mp4: Add ISOBMFF to format description
Basic support, can also do CER and DER but without any extra validation.
No schema support.
Redo format doc.md usage a bit, now format/<dir>/<format>.md instead.

Remove bitio.Buffer layer. bitio.Buffer was a kitchen sink layer with helpers
now it's just a buffer and most functions have been moved to decode instead.
bitio package now only have primitive types and functions simialar to standard
library io and bytes packages.
Make nearly eveything internally use bitio.Bit* interfaces so that slicing work
correctly this will also make it possible to start experimenting with more
complicated silcing helpers, ex things like:
breplace(.header.bitrate; 123) to get a new buffer with bitrate changed.
