Configuration files

• [x] requirements.txt including API and Testing libraries
• [x] .gitignore will include pyenv/ as this will be my env manager
• [x] github actions workflow to automate testing on push and pull request

pytest seems to require a config file as well to properly reroute the testing in the src folder

Added a Github Actions workflow running on the latest 3 secure Python release (3.8, 3.9, 3.10)
