Reworked how the flea market categories are calculated, instead of trying to be smart and add/remove in a cache as offers are created, calculate the categories when needed

Categories:
Are now much more accurate
take into account when player is below flea unlock level
Any with a (1) and no offers have been fixed
Take into account when offers are barters + barters are filtered out

Skip items with a type of `node` during flea assort generation
