[minor] interface flexibility

[liamhuber]

Finished the storage refactoring, allowing non-canonical file paths to be specified, allowing children of StorageInterface to take **kwargs on their methods, and adding tests and docstrings.

I don't currently expose explicit storage interfaces to the user on the Workflow.create menu, but this is probably a good idea in the near future as it's a necessary object for using custom save/load paths. It (and the abstract base StorageInterface and convenience generator available_backends) is (are) now included in pyiron_workflow.__init__ though, so it's part of the API and pretty easy to access.
