CHANGES: - Add a little executable to benchmark inflation into the distribution (@dinosaure, mirage/decompress#93) - Add instructions for running benchmark (@gs0510, mirage/decompress#94) - Clarify the description (@XVilka, mirage/decompress#96) - Improve the benchmark and outputs (@dinosaure, @gs0510, mirage/decompress#95) - Avoid allocation of distance table (@Engil, @dinosaure, mirage/decompress#97) - Swapping from arithmetic to logical bitshifts on `d.hold` (@clecat, mirage/decompress#99) - Make the use of all `Higher.compress` arguments (@vect0r-vicall, mirage/decompress#103) - Apply ocamlformat.0.16.0 (@dinosaure, mirage/decompress#105, mirage/decompress#107) - Improve Lz77 algorithms (@dinosaure, mirage/decompress#108) **breaking changes** the deflation expects a new window: `De.Lz77.make_window` instead of `De.make_window` (which is twice larger to improve the compression algorithm) Depending on the level and your corpus, we did not observe performance regression on deflation (and mirage/decompress#97 improves a lot performances). An higher level is slower (but the compression ratio is better). We advise, by default, to use the level 6. Note that the user is able to make its own compression algorithm according to his corpus. An example of such implementation is available on the new `decompress.lz` libraries which fills a queue and compress the input. **breaking changes** decompress expects a level between 0 and 9 (inclusive) (instead of 0 and 3). - Add tests about level compression (@dinosaure, mirage/decompress#109) - Add level on GZip layer (@dinosaure, mirage/decompress#110) - Provide a `ctypes` reverse binding (@dinosaure, mirage/decompress#98) - Provide a binary `decompress.pipe` which can compress/uncompress with deflate, zlib or gzip format.

According yallop/ocaml-ctypes#660, this is a way to produce a reverse binding of
decompressto be usable by C sources.
