Add runtime summary to calibration metadata

See merge request detectors/pycalibration!418

It was just a warning for summary.rst, but might as well.

Fix/DSSC DARK was missing from the new mapping modifications

See merge request detectors/pycalibration!425

Add test for webservice.merge

See merge request detectors/pycalibration!423

Remove duplicate operation_mode parameter in FastCCD notebook

See merge request detectors/pycalibration!422

[MAPPING][DARK][INJECT] PT2 Update injecting functions and Dark notebooks

See merge request detectors/pycalibration!416

Fix/3.0.0-test04 on max-exfl017: proposal-yaml, AGIPD correct, PnCCD notebooks, and DSSC dark

See merge request detectors/pycalibration!420

Make get_dir_creation_time use files creation dates, not folder

See merge request detectors/pycalibration!421

We cannot rely on the directory creation date, as it might get modified with filesystem upgrades. File modification dates are conserved though (not creation date), so we must use these when the information is not available from run metadata

See merge request detectors/pycalibration!419

Feat/202 (save calibration pipeline parameters in YAML file)

See merge request detectors/pycalibration!409

This metadata file subsumes the old retrieved constants YAML file.  The commit includes some refactoring centered around pathlib.

Fix/Unused Variables

Going through some of the warnings my IDE is throwing up so I'll probably end up doing a couple of these tiny pull requests.

- `cal_tools/cal_tools/agipdlib.py`: `corr_bools={}` setting keyword arguments to mutables isn't a great idea since the state can persist across function calls, maybe in this case that was the intention but it usually isn't. Changed it to `None` and then set it to a dict if no argument is given.
- `cal_tools/cal_tools/lpdlib.py`: `self.cnl = True` was set, but it looks like that should have taken its value from the `correct_non_linear` argument, set it to that.
- `cal_tools/cal_tools/metrology.py` an `offset` is defined but never applied to the coordinates. Similar code appears throughout the file so I just did the same thing there as well, think it should be correct.
