Incremental / partial compression

Right now, compressing a room requires holding its entire state in RAM, which can become arbitrarily large. I don't know the internals of the compression algorithm, but given that state...

Please add detailed information to the README for someone, who has never used rust before, how to start the script: # build this rust script 1. install Rust - on...
