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.

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.

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.

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.
