Introduces Linux release!
Linux users can use either the .appimage file or run ./opti after extracting the .tar.gz

Note: transparent windows on linux is a little finicky. I have added a reload function bound to the 'r' key, which should fix the background
running on linux requires giving executable permissions to the .appimage file or opti file in the .tar.gz

Added

•  Linux build
• r key to reload
