Pydantic ModelEntry

[lewisblake]

Change Summary

Implements ModelEntry in terms of pydantic. Removes classes DictStrKeysListVals and DictType from _lowlevel_helpers.py in pyaerocom. There were a few attributes which, while not declared in ModelEntry, where given as kwargs and were critical to the functionality of the class in downstream processing. These have been added as attributes to ModelEntry. You may notice that many of these attributes are also given as attributes in ColocationSetup. This is because the current functionality copies these attributes from the instance of ModelEntry and assigns them to the corresponding attribute in ColocationSetup which is specific to a (obs, model) tuple in HasColocator.get_colocator(). This should be redesigned in the future to minimize confusion.
