add form information as an attribute in the tree

[violll]

Will have to get the tree using dict_to_tree rather than list_to_tree, but that shouldn't be too difficult to manage

[violll]

This isn't going to work using a dict because the keys will appear identical. Experiment with polars_to_tree

[violll]

Not possible. On another note, I've discovered pokeapi, which I think will suit my needs perfectly
