**Notes**

* GitHub Actions CI test suite added
* Windows not passing currently, fixes to come
* Note that pwsh shell implementation was using the subprocess 'universal_newlines' arg - this has been
removed. This was causing `execute_shell` to return an str-type stdout/stderr tuple, rather than
bytes as every other shell impl does, and this was causing tests to fail.

**Notes**

Last round of Py3 updates (not counting further bugfixes found from testing).

Please take note if you notice any changes in performance in Py2. This release includes a number of changes
from methods like `iteritems` to `items`, which in Py2 means a list construction rather than just an iterator.
Tests have shown performance to be identical, but you may find a case where it is not.
