Padding could end up double.
Remove to*range($pad) as it probably just confusing to be able
to pad an existing range, what to show in hexdump etc? zero bits
that do not actuall exist at that range?
Add tests and binary stdout support to tests
Fixes missing function errors for fq builtins
Add includes to fix some other missing function errors
Add COMPLETION_TIMEOUT env to increase comepletion timeout during test using -race
Now all regexp functions should work similar to string version for buffers.
Added scan_toend that works as scan but outputs buffer from match to end of buffer,
useful when trying to decode a format and you dont know or care to limit.
