Compression identifier

Compress

Decompress

TODO: https://github.com/well-typed/grapesy/issues/57. We need to deal with decompression failures.

Uncompressed size threshold

Compression is only useful for uncompressed data sizes satisfying this predicate.

Which algorithms should be offered (in this order) to the peer?

This should normally always include Identity (see choose); but see insist.

Choose compression algorithm

We will run this only once per open connection, when the server first tells us their list of supported compression algorithms. Unless compression negotation has taken place, no compression should be used.

This cannot fail: the least common denominator is to use no compression. This must be allowed, because the gRPC specification anyway allows a per-message flag to indicate whether the message is compressed or not; thus, even if a specific compression algorithm is negotiated, there is no guarantee anything is compressed.
