bafd1f564e decode,fuzz: Signed integer (S) read require at least one bit
Otherwise there is no sign bit and it will panic on shifting.

Maybe should require 2? now -0 and +1 hmm

768df3012c interp,decode: For struct use map to lookup field
Will make it faster for struct with logs of fields and seems to
not cuase any significant difference for small structs.

All this really needs a rewrite somehow, maybe refactor into interfaces somehow? getting messy.

725c8e83ab macho: Split into macho/macho_fat, fix offset issue and add string decoding
Split fat macho into own decoder macho_fat. This also fixes issue with section
offset etc not being correct as they are from the start of each embedded file.

Make all address and offset field be in hex.

Decode __cstring, __ustring and __cfstring sections.

Fix LC_ENCRYPTION_INFO_64 missing pading issue.

Skip ranging for __bss and __common as they dont have any data in the file.

Simplifed magic handling a bit and add symbols.

Simplified state struct field, had redudant struct.

840292ba6e decode: Simplify compound range sort behaviour
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.

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.

7b27e506f1 mp4,bitio: Fix broken pssh decoding and add proper reader cloning to bitio
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

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.
