No longer maintained, use jruby/jzlib instead

[headius]

Hello to @ymnk and anyone else who might be out there!

As this repository seems to have been abandoned for a very long time, the JRuby team now maintains and releases an updated version from https://github.com/jruby/jzlib. We have fixed bugs over the years and added basic JPMS module support. It is an integral part of JRuby, and we will continue to maintain it.

Users interested in updates should probably switch to our version, unless @ymnk comes back and would like to resume working on this version.

JRuby's jzlib is available from Maven as org.jruby:jzlib:1.1.5 (current version).
