handling compressed files

[bdnbje]

This is probably out of scope of this project but since its coming around being a very good archiver can a way to recompress zlib streams on the fly be possible to be a added feature in this project. zlib is the most common compression algorithm used in files png pdf a lot of generic data used in a regular file system uses zlib streams if there could be a way to handle them on the fly could make dwarfs state of the art. Theres already some projects that do handle this task like https://github.com/deus-libri/preflate, https://github.com/schnaader/precomp-cpp and https://github.com/google/grittibanzli
