Introduced a UserScript that replaces the "Buy on Amazon" button with a "Buy at Morawa" button on Goodreads book pages. This script fetches the ISBN of the book and links to Morawa.at using the ISBN. Added LICENSE file with MIT license and created a README that includes installation and usage instructions.
