bz3_compress generated file can not pass test

[synodriver]

./bzip3 -t ./new.bin 
Failed to decode a block: Burrows-Wheeler transform failed

However, bz3_decompress can decompress that

Expected behaviour; bzip3 command line tool and bz3_compress use a different frame format. This is because bzip3 the command line tool might not know the length of the data stream upfront and bz3_compress always knows it beforehand.

Ok, I see. Should we add a note for that?

I'm in process of adding relevant documentation.
