8e0dde03d0 decode: Support multiple format args and some rename and refactor
This will allow passing both cli options and format options to sub decoder.
Ex: pass keylog option to a tls decoder when decoding a pcap.
Ex: pass decode options to a format inside a http body inside a pcap.

Add ArgAs method to lookup argument based on type. This also makes the format
decode function have same signature as sub decoders in the decode API.

This change decode.Format a bit:
DecodeFn is now just func(d *D) any
DecodeInArg renamed to DefaultInArg

9b81d4d3ab decode: More type safe API and split scalar into multiple types
Preparation to make decoder use less memory and API more type safe.
Now each scalar type has it's own struct type so it can store different
things and enables to have a scalar interface.
Also own types will enable experimenting with decode DLS designs like
using chained methods that are type aware.

c3a0686c9e mp3_frame_tags: Refactor and rename xing format to mp3_frame_tags
Make more sense to use a more general name when there is both info and xing
and possibly vbri in the future. Also both xing and info seems to have extension
fields

Remove some old tests that are not really needed anymore.

2de875393a mp3_frame: Fix issue calc frame size for some configs
Seems have to use the 144000*bitrate/sameplrate to get correct size or
one would miss one byte (odd size rounded to even?)

cf15661e9c mp3_frame: Add LSF support and fix incorrect main data handling
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.

1ddea1ada3 interp,format: Refactor registry usage and use function helpers
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.

a6a97136b7 decode: Cleanup Try<f>/<f> pairs
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.

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

7c5215347d bitio,decode: Refactor bitio usage and make buffer slicing more correct
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.

2fc0a71a47 decode: Refactor scalar usage
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.
