package cobs

to_cobs ?delim bytes is a bytes containing a COBS-encoded representation of the given bytes, using the provided delimiter (defaults to '\000').

The encoded representation will not end with a delimiter byte; if it is necessary, you must append it to the output of to_cobs.

from_cobs bytes is a bytes containing the result of COBS-decoding the given bytes, using the provided delimiter (defaults to '\000').

bytes is expected to not end with the delimiter byte; if present, it should be stripped before passing the data to from_cobs.
