Feels less cluttered, easier to read and more consistent.
Still keep tovalue, tobytes etc that are more basic functions this
only renamed format related functions.
Also there is an exceptin for to/fromjson as it comes from jq.
Also fixes lots of spelling errors while reading thru.
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.
raw format was a hack to skip decoding to be able to get a binary using tobyte etc.
Now you can do fq -d bytes ... instead of fq -d raw 'tobytes | ...'
Markdown is used as is in online documentation and in cli the markdown decoder
is used to decode and the some jq code massages it into something cli friendly.
Was just too much of a mess to have doc in jq.
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.
