BaseBatterySubmodel

[rtimms]

Make a BaseBatterySubmodel that performs things like checking domains, e.g.

        ok_domain_list = [
            "Negative",
            "Separator",
            "Positive",
            "Negative electrode",
            "Negative electrolyte",
            "Separator electrolyte",
            "Positive electrode",
            "Positive electrolyte",
            None,
        ]

so that BaseSubmodel is more general. Useful for training etc. to not be restricted to battery things when using submodels.

We could consider getting rid of those checks.

Following our experience with the coord_sys, I think we should keep some checks somewhere in the battery submodels. But certainly not in the BaseSubmodel class.
