pip install from .tar.gz broken - HISTORY.md not packaged

[jantman]

setup.py reads in HISTORY.md, but that file is not present in the `1.2.2 source tarball distribution on PyPI. As a result, installing from source/tarball fails.

This can be verified by trying to install the .tar.gz currently on PyPI, or just looking at it and confirming that HISTORY.md is not included. It looks to me like this needs a MANIFEST.in file.

DEPRECATION: --no-binary currently disables reading from the cache of locally built wheels. In the future --no-binary will not influence the wheel cache. pip 23.1 will enforce this behaviour change. A possible replacement is to use the --no-cache-dir option. You can use the flag --use-feature=no-binary-enable-wheel-cache to test the upcoming behaviour.
