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
Rewrite non-sub-repl queries as "q" -> ".[] | q" and pass in inputs as array.
Before each input did an eval.
Also fixup error message a bit, skip line:column when they dont make sense.
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.
Related to #20
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.
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.
