Work around legacyScreenSaver bug

Added a bodge to terminate the Flying Toasters right before the OS does. This in turn appears to triggers the legacyScreenSaver service to quit and release its memory. Testing was limited to macOS Sequoia.

Rebuilt binary for Apple Silicon support

• Corrected an issue where the screen saver could flash a gray screen on launch

Initial Release

Compatible with Mac OS X Mavericks (10.9) to macOS Big Sur (11.0)
Explicit functional testing on Mavericks, Catalina, and Big Sur. Other versions of Mac OS in between are expected to function however not tested explicitly.
