Replace Travis with GitHub Actions and update linting configuration f…

…or isort v5 (#257)

* Integrate frontend & backend into 'ci' workflow

* Fix lint errors due to using isort 5.0

* Prior to version 5.0.0, isort wouldn't automatically traverse directories. The --recursive option was necessary to tell it to do so. In 5.0.0 directories are automatically traversed for all Python files, and as such this option is no longer necessary and should simply be removed.

* Add python_requires to setup.py
