update to use newer versions of dependencies (#87)

* remove deprecated `scipy` functions in favor of `numpy` ones * re-format with latest version of `black` * lint with `ruff` * add `pyarrow` dependency as required by new `pandas` * pass tests w new versions of dependencies * test via GitHub actions, not Travis * remove Travis test file

 The format is based on `Keep a Changelog <https://keepachangelog.com>`_.
 
+1.5.0
+-----
+- Remove use of deprecated ``scipy`` functions like ``flip`` to use ``numpy`` alternatives instead (fixes [this issue](https://github.com/jbloomlab/dms_variants/issues/86)).
+- Re-format code with latest version of ``black``.
+- Lint with ``ruff`` rather than ``flake8``
+- Add ``pyarrow`` as dependency as required by ``pandas``.
+- Tweaks to work with new versions of ``pandas`` and ``plotnine``
+- Test with GitHub Actions rather than Travis CI
