A replacement for the builtin zipfile module, with fast, C-based zipfile
decryption

czipfile is a replacement for Python's builtin "zipfile" module, and \ 
provides
much faster, C-based zipfile decryption. The code is actually 95% identical to
Python 2.6.5's Lib/zipfile.py, with some very minor modifications to allow it
to compile in Cython, and the _ZipDecrypter class adapted to take advantage of
native C datatypes.

Package provided by Kimihiro Nonaka in PR 51326, with some cleanups by myself.
(Fix typo in MASTER_SITES, pkglint.)
