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.
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 | ...'
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.
