Fix bug and little improve performance

• Add a window_bits parameter in Deflate module
• Remove compilation with cppo (use -inline option instead)
• Fix bug for last block in Deflate
• Little optimize a compute of CRC in Inflate
• Fix Manual mode in Inflate
• Fix dist computation in Inflate (infinite loop)
• Optimize computation of tree (literal and dist)
• Add unit test (compare with camlzip)
• Fix bug in reverse package merge algorithm in Deflate module
• Use ocaml/ocaml-travisci-skeleton

Improve interface and optimization

• Use CPS style to compute inflate and deflate like xmlm and ocaml-imap
• Optimize inflate window like ring-buffer in ocaml-mm
• Optimize compute of Adler 32 with cppo
