0.5.0

Added

• Support for LZMA, Bzip, and Gzip output compression (thanks to niffler). This is either inferred from the file extension or manually via the -O option.
• Option to specify the compression level for the output via -l

Changed

• Use a Vec<bool> instead of HashSet to store the indices of reads to keep. This gives a nice little speedup (see #28), A big thank you to @natir

Fixed

• Restore compression of output files [#27]
