Compatibility with JavaFastPFOR

[nedtwigg]

One common "rich client" usecase is for a server to do expensive compression, pass the shrunk result along the network, and then the client does relatively cheap decompression. Is FastIntegerCompression.uncompress compatible with the output of any of the algorithms in your other excellent integer compression libraries? That might be something worth advertising at both ends.

Currently, no such claim is made. It would indeed be a good idea to investigate.
