Compression and decompression in the gzip and zlib formats

This package provides a pure interface for compressing and decompressing streams of data
represented as lazy ByteStrings. It uses the zlib C library so it has high performance.
It supports the "zlib", "gzip" and "raw" compression formats.

It provides a convenient high level API suitable for most tasks and for the few cases
where more control is needed it provides access to the full zlib feature set.
