split-off HW handling

[wvlothuizen]

This PR is intended to split off the hardware handling from the files below, as an initial step to handle hardware in a separate 'layer':

• CCLight_Transmon
• device_object_CCL
• detector_functions

The following still need a similar split-up:

• mw_lutman
• ro_lutman
• flux_lutman (which of the 3?)
• sweep_functions

Some class and file names have been changed to better reflect the current situation (e.g. "CCLight" is removed), but to maintain compatibility the old names and locations are still supported through 'compatibility imports'.

This PR takes a lot of care to not break anything for the end user, but in the slipstream of this PR:

• support for CCL/QCC was removed, since OpenQL no longer supports this architecture
• a lot of old cruft was cleaned up
• some long parameter lists are reformatted for improved readability
• some type annotations are added in order allow better understanding, improved checks and improved code navigation by PyCharm
• deprecation warnings were added to apparently unused code
• some disabled CI tests were fixed and enabled
• some CI deprecation warnings were solved
• fixed codacy and codecov CI integrations

A subsequent step in a follow-up PR would be to integrate the HW management for single vs. multi qubit experiments, and more clearly assign the responsibilities of all the components involved

@MiguelSMoreira I guess it would be advantageous to merge this before new developments will start to prevent new conflicts now things have moved around. I merged with the recent updates in branch 'develop' and fixed CI. It would be good to take a special look at the last few commits that fix conflicts and CI. Maybe other people should also review, I'll leave that for you to decide.
