Coding up a circular buffer with Jez

More coding with Jez and Andy. We're continuing working on our gunzip clone: we know we will need to be able to look back while we are encoding at recently-written bytes, so this time we're writing a look-back buffer. We could use a crate to provide a circular buffer, but what would be the fun in that? The code is at https://codeberg.org/andybalaam/ggunzip.
