[pyup-bot]

This PR updates zipp from 0.6.0 to 3.0.0.

Changelog

3.0.0

======

44: Merge with v1.2.0.

2.2.1

======

43: Merge with v1.1.1.

2.2.0

======

36: Rebuild package with minimum Python version declared both
in package metadata and in the python tag.

2.1.0

======

32: Merge with v1.1.0.

2.0.1

======

30: Corrected version inference (from jaraco/skeleton12).

2.0.0

======

Require Python 3.6 or later.

1.2.0

======

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.

1.1.1

======

43: Restored performance of implicit dir computation.

1.1.0

======

32: For read-only zip files, complexity of ``.exists`` and
``joinpath`` is now constant time instead of ``O(n)``, preventing
quadratic time in common use-cases and rendering large
zip files unusable for Path. Big thanks to Benjy Weinberger
for the bug report and contributed fix (33).

1.0.0

======

Re-release of 0.6 to correspond with release as found in
Python 3.8.
