[feature request] minecart scanning

[esotericist]

for entities you can scan for passive mobs and hostile mobs, but i often want to scan a mineshaft for chest carts. it'd be nice if we could do that.

i suppose ostensibly it could also cover other things, but i can't recall ever having wanted to scan for a boat, and i'm not sure what else this could cover. (general loot storage objects, whether entity or block entity? dunno)
