pokemaster.pokemon.Pokemon should not bind to a session

[kipyin]

pokemaster/pokemaster/pokemon.py

Lines 29 to 33 in 80a839d

	@attr.s(auto_attribs=True, repr=False, cmp=False)
	class Pokemon:
	"""A Pokémon."""
	session: ClassVar = get_session()

Binding a pokemaster.pokemon.Pokemon object to a db session couples the class with a db schema, and having them completely separated is much preferred.

But if we remove this class var, how can properly instantiate a pokemaster.pokemon.Pokemon instance?

E.g., how do we get the correct database for the following helper class method?

pokemaster/pokemaster/pokemon.py

Line 301 in 80a839d

species = util.get(cls.session, tb.PokemonSpecies, id=species_id)

I think, we should keep all the database mess in pokemaster.query module, including the (only) function, pokemaster.session.get_session(). If we need to change the db, use pokemaster.query.bind_session().
