Since it is a just a stream-based compressor like gzip, it is relatively
easy to add support. I will take a look this. There might be some
performance issues when accessing a lot o files with lzip packed
archives since it seems as the library does not support internal state
save/restore for seeking but for usual use cases it should be fast enough.

It is not abandoned, but I don't have the need for much improvement
either. It works fine for me. From time to time there is native support
for some new compressor, but usually for more complex formats I rely on
extfs integration which is often slow, but good enough on the other hand.

Best regards,

Ralf
