GitHub actions testing (#9)

Moving from Travis to GitHub actions

* Add GitHub actions to build package
* Change Python versions to 3.x
* Use pytest instead of nose
* Drop 3.4 testing and test uploading of results
* Test junit reporting
* Move Pypi to use secret keys
* Add skip_existing flag for dev deployments
* Update test results dir
* Add production deployment
(Should only run on master branch and tagged commits)
* Only run production on tagged commits v2
