Librarian Tweaks

The mod reworks what librarian villagers sell. Each trade level offers books with a set chance of being a book trade, and the books offered are limited to lower-tier enchantments. At the first level, about two in three trades are a book trade, and those books are only common ones up to enchantment level 2, across 9 trades. At the second level, a similar chance applies, but the books are uncommon and capped at a lower enchantment level, across 7 trades.

At the third level, about two in three trades are again book trades, and the books offered are rare but at worse enchantment levels, across 5 trades. The fourth level keeps a 67 percent chance for rare books at lower levels, across 3 trades. The changes affect only what librarians sell, so other villager professions and loot are not altered.
