Description

• Add automated tests (basic ones).
  • Included test certificates are NOT valid and are thus not a leakage of confidential data.
• Code formatting to MOSTLY pass pysh/black/pycodestyle.
• GitHub action to cover pytest.
• Added pytest as dependency to requirements.txt.
• Minimum Python version is now 3.6 (since I used f-strings).

The provided pytest tests pass for me locally on the Ubuntu 22.04 machine, but not on the remote. The printing is producing a different output for some reason (best guess at this stage).

@petedyerarm - thanks for help again, issues is in the last line - cbor print does it with \r\n (aka CRLF). But, I am guessing depending on your git settings or something - it gets turned into plain /n (aka LF) and then it's not matching anymore. Removed the \r from cbor printing.
