Rework time helpers to use new functions
Fix panic in tar decoder where sym value might be missing
Still not very happy about the API but it's getting better.
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
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

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.
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
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.
Track size/count instead of just sizes which should decrease memory usage
making count sanity check unnecessary.
Fixes issue with huge mp4 files (80gb+) with lots of samples.
Move scalar into own package.
Split scalar code into decode related scalar code (that reads etc) and
scalar code that just transform the scalar value.
Use a scalar.Mapper interface instead of just a function.
Make mappers, assert and validat impement the interface.
