Feature suggestion : adding loot to structures

[ImXyper]

for example, if im looking for a desert temple nearby, i could make it only search for temples that have a notch apple inside

@Cubitect since you recently introduced structure parts, is it possible to directly get loot from chests? (or export chest locations for external checking with loot-checker for example) I think all requirements are in place, just item names and loot tables and cubiomes-viewer will look for egaps! (requested by @adabugra, he wants egaps from nether since overworld has modified terrain)
