LZW en- and decoding that goes weeeee!

This library, written in purely safe and dependency-less Rust, provides encoding and decoding for lzw compression in the style as it occurs in gif and tiff image formats. It has a standalone binary that may be used to handle those data streams but it is not compatible with Spencer's compress and uncompress binaries (though a drop-in may be developed at a later point).

Using in a no_std environment is also possible though an allocator is required. This, too, may be relaxed in a later release. A feature flag already exists but currently turns off almost all interfaces.
