We should be able to trash/delete unwanted cards

We should have the possibility to delete (or convert into points) cards whenever we want, even if it means we could remain with 0 cards of the same type. This could also be useful in cases where you get a card in an unwanted language and want to remove it. It is a simple functionality that already exists in pokemon go. Moreover we should also be able to sell/delete/trash unwanted accessories, like playmats or other stuff from the shop.
