051a70bd4b interp: Change bit ranges to use exclusive end 
All other ranges and slicing uses exclusive end so i think it make sense
to make it consistent.

Update docs and add additional example for non-byte-aligned field.

Also fixes issue showing zero bit ranges as start-NA.

Also change the option help a bit, maybe medid and support is confusing, we

e77f776999 decode,interp: Rename unknown gap fields from "unknown#" to "gap#" 
Think it makes it clearer and also less likely to collide with a field
name a deocder wants to use.

c93301fc70 raw,bits,bytes: Replace raw format with bits and bytes format that decode to a binary 
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 | ...'

cf15661e9c mp3_frame: Add LSF support and fix incorrect main data handling 
Some mpeg versions use LSF (low sampling frequency) when encoding
low sample rates which changes a bit how the side info is layed out.

Also skip trying to separate data and other_data as after reading up
a bit on how main data begin and bit reservoir works i think it was done
incorrectly. To know the real audio data length i think you need to decode
the huffman tables. Instead just have a "audio_data" field which are the
bits with audo data for current and possibly following frames.

Update spec from https://raw.githubusercontent.com/ietf-wg-cellar/matroska-specification/master/ebml_matroska.xml
Allow unknown ids, decodeas "unknown" type with just binary data
Change "type" field to just a string, there is no type id number.
Make all type field symbols consistently lowercase
