Better Bookshelves

Update to 22w46a

Rename config options:

• snake case instead of camel case
• book_texture -> per_book_texture (true/false) (default (true)
• [new] book_type_comparator_output (true/false) (default false)
• when a new book is added, a comparator will output a signal based on the book type (1: book, 2: book and quill, 3: written book, 4: enchanted book)
