Upgrade to Python 3.7+ syntax

[dolfinus]

• Run pyupgrade --py37-plus ./**/*.py to upgrade Python 2.7 syntax to 3.7+
• Replace %s and .format() syntax with f-strings
• For logging use %s string syntax, but without explicit "msg" % (variables,) - let logging do this if logging is enabled for a specific level
• Convert # type comments to type hints, replace List[type], Optional[type] and Union[type1, type2] with list[type], type | None and type1 | type2 (using from __future__ import annotations).
• Use os.fspath instead of str to convert Path-like objects to string path representation
• Update examples to use logging instead of print
