051a70bd4b interp: Change bit ranges to use exclusive end
All other ranges and slicing uses exclusive end so i think it make sense
to make it consistent.

Update docs and add additional example for non-byte-aligned field.

Also fixes issue showing zero bit ranges as start-NA.

b08ef00dd1 decode,interp: Refactor format groups into a proper struct
Replaces []Format with a Group type.
A bit more type safe.
Breaking change for RegisterFormat, now takes a first argument that is a "single" format group.
Lots of naming cleanup.

This is also preparation for decode group argument which will enable doing intresting
probing, ex a format decoder could know it's decode as part of probe group  (html could
be probed possibly), or have "arg probe" group for decoder who inspect args to know
if they should probe (-d /path/to/schema etc) to enable nice CLI-ergonomics.

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.

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.

e8dc7112b6 ipv6,icmpv6: Add decoder
Refactor to use groups between network layers to make them less coupled and reusable:
link_frame (ethernet etc)
inet_packet (ipv4,ipv6 etc)
ip_packet (tcp packet (not stream), udp segment etc)

Rename data to payload as i think it makes more sense for network data

0829c167cc asn1_ber: Add decoder
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.

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.

Make mappers, assert and validat impement the interface.
