Getting special pokemon sprites (shiny/back/female) requires manual folder creation

[AtomToast]

If you want to access the different sprites of a pokemon for example by using:
p = pb.pokemon_sprite("back/3")
(same with using api.lookup_sprite and SpriteResource)
You'll get a "FileNotFoundError" unless you manually create the "back" folder inside the .cache/pokebase/sprite/pokemon folder

This should be fixed now with the latest commit.

I'll close when I push to PyPI.
