Fixes#97201
Instead of using and arbitrary fixed size for the internal buffer,
the remaining available bytes of the internal `RingBuffer` is used.
Also add unit tests for `StreamPeerGZIP`.
We don't use that info for anything, and it generates unnecessary diffs
every time we bump the minor version (and CI failures if we forget to
sync some files from opt-in modules (mono, text_server_fb).
Putting data results in writing the compressed/decompressed output into
a RingBuffer.
You can retrieve the content of the RingBuffer via get_data.
Support both gzip and deflate.
