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.
I think this is closer to what one would expect.
With this fq -d bytes 'scan("...")' will match as a binary and also return binaries,
before as raw decode value one would have to use tobytes to get the 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 | ...'
