Move to pyproject.toml

[dbrakenhoff]

Note: I accidentally added everything to this PR.

So this does a bunch of stuff:

• add support for pastas>=0.23
  • remove usage of ps.TimeSeries objects
  • add pastas.validate_oseries and pastas.validate_stresses options (can be turned on/off on method and connector level)
• move to pyproject.toml
• test pastastore against multiple versions of pastas (currently 0.22.0 (master) and 0.23.0 (dev))
• drop official testing for arctic and pystore (this was making my life difficult). All the code and tests are still available but are not run automatically on GH. It is therefore recommended to use PasConnnector.
• update notebooks
• update tests

Closes:

• 76

• 77

• 78

• 79

Note: the tests will not pass until some of pastas current PRs are merged.
