Fxied a bug in LZNT1 compression where it failed if the last chunk should be uncompressed and the output buffer was exactly large enough to fit the data. Also probably provides a slight speed-up. Also removed some old commented-out code.
Fixed a bug in Xpress decompressor where it could not properly handle when the compressed stream ended with an improper set of flags and no more data (produced by both RTL and my code). Also fixed my compressor to not output improper flags in this case.
