Detailed Description

A simple byte-based runlength encoder/decoder.

Note that the encoded size may actually be bigger then the original size for random data!

get a safe size for the destination buffer

Get some safe destination buffer size for runlength-encoding.

This actually can be up to twice as big as the source buffer for completely random data!
