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.

cae288e6be format,intepr: Refactor json, yaml, etc into formats also move out related functions
json, yaml, toml, xml, html, csv are now normal formats and most of them also particiate
in probing (not html and csv).

Also fixes a bunch of bugs in to/fromxml, to/fromjq etc.

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.

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

Related to #282

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.
