Dimensions Villagers

With the newest 1.14 feature, we could create new villagers using new job site blocks like end villager who could trade shulker shell, elytra, chorus fruit, dragon head, or end crystal; or nether villager who could trade nether quartz, nether warts, soul sand and magma block.

This new job site block would be obtainable only on end city/nether fortress and couldn't be craftable.

Of course some prices should be expansive and some trades very limited (elytra).
