Meta objects had no way of creating datasets, which blocks workflows.

Solution

Added a simple create dataset function to the DatasetMeta object, with tests.

Changelog

Implemented previously NotRaisedException raising function create_dataset on DatasetMeta
Added unit tests for creation of datasets.

not blocking but I feel like this has some crossover with the pydantic validation functions and we could reuse them.

LGTM. I think stuff like the Query's should be an @property so they can just be called like dataset.items.where() (ie without the function call). Although I'm not too sure on datasetmeta having a dataset field, maybe hidden field? Not part of this PR though.
