ms3 v2.1.0: Loads of code cosmetics (and support for pandas 2)

This update includes a few minor bug fixes but some heavy updating of the code internals:

• pandas>=2.0.0 is now supported
• the @function_logger decorator has been removed and replaced with a function argument that defaults to the
  module_logger
• all modules which have seen a commit since the previous tag have been fully linted using pre-commit hooks
• the filelock problem that made a couple of test fail under Windows since the early days has been resolved (by using
  pytest's tmp_path fixture instad of NamedTemporaryFile).
• make_ml() (responsible for creating measure tables) was refactored and should be much more legible (and easier
  to adapt and extend in the future)
