GitHub actions CI workflow

[jhdark]

Proposed changes

This would allow us to have Continuous Integration within Github using actions. Another amendment can be made to export the codecov report however this would require access to a secret token. At the moment this only runs on PR's however could be amended to run on all push operations to certain branches

Can you add the upload to codecov please?
This is the command we need to run:

curl -Os https://uploader.codecov.io/latest/linux/codecov

chmod +x codecov
./codecov -t ${CODECOV_TOKEN}

I've added the CODECOV_TOKEN secret to the repo.

You need to modify the pytest command accordingly:

pytest test/ --cov festim --cov-report xml --cov-report term
