set compression level for individual files in zip-fs

There should be a way to set the compression level in zip-fs modus, for all files or for single ones.

You're right, I'll add an optional parameter in add* methods.

Hi, is there any update on this? This option is important, especially when trying to create an epub file, where we need to set compression level to 0.

P.S. Thanks a LOT for this awesome library

It's possible since the version 2
