Replace "python setup.py" builds with "python -m build"

Found left-over remnants of `setup.py` install and updated with current
build method using `build` package.

Not sure how `Makefile` and `release.py` had access to `twine`
previously since it was neither installed within nor part of
`Pipfile`'s `[dev-packages]`. So, updated `Pipfile` with both `build`
and `twine`.

**`Pipfile.lock` has not been updated.**
