New Villager Profession: Scribe

A unique villager profession that master level librarians can become. A scribe has one trade: creating copies of the enchanted book in their lecturn. This would remove the need to have massive trading halls dedicated to enchanted books. 

Mechanic:
This only affects librarians that have reached master level.
Placing an enchanted book in a lecturn will turn that lecturn's librarian into a scribe. Removing the enchanted book from the lecturn will return the scribe to a librarian.
All trades made as a librarian will count as trades made when they are a scribe and vice versa. Changing from librarian to scribe and vice versa will not refresh their stocks. Example 1: Player buys paper (16 trades) from librarian until the librarian is out of stock. If the player places an enchanted book on the lecturn and the librarian becomes a scribe, their trade would be "out of stock" until their next stock refresh. Example 2: Player buys glass blocks (3 trades), clock (1 trade), and name tag (4 trades). If the player places an enchanted book on the lecturn and the librarian becomes a scribe, their trade would have 8 trades until their next stock refresh.

Trades:
Slot 1(only slot): Enchanted book (whichever is in lecturn) - Cost: 25 emeralds (15 for "Hero of the Village") - Trades in stock: 16

Additional Traits:
Since scribes are a temporary profession, they would not be affected by zombification curing.
As a villager, they would still be affected by "Hero of the Village" and grant a discount.
