Log Message:
py-zipp: update to 1.2.0.

v1.2.0
======

#44: ``zipp.Path.open()`` now supports a compatible signature
as ``pathlib.Path.open()``, accepting text (default) or binary
modes and soliciting keyword parameters passed through to
``io.TextIOWrapper`` (encoding, newline, etc). The stream is
opened in text-mode by default now. ``open`` no
longer accepts ``pwd`` as a positional argument and does not
accept the ``force_zip64`` parameter at all. This change is
a backward-incompatible change for that single function.

v1.1.1
======

#43: Restored performance of implicit dir computation.
