[Compatibility] Mark food jokers

[Lykrast]

So mods like Paperback or Cryptid mark food jokers with a pools = { Food = true }, for compatibility, so that could be added to jokers like Strawberry. I'm not sure if all strawberries would qualify spiritually but at least some of them would.

Maybe could also be used to make a proper "Strawberry" pool which could clean up a bit 1UP and Seeds, like potentially allow some other mod to count its strawberries. I don't know the exact workings of it but I know Entropy uses it with its Capsule Machine to generate one of its random dice jokers.
