Morse Code Simulator v2.0

Two years after creating this neat tool, I've decided to go back and update it to my more modern standards. This includes a quality-of-life pass, fixing long-standing issues, making the desktop versions more professional, and open-sourcing the code.

Morse Code Simulator has always been one of my favorite creations, and I've felt a bit guilty that it's not as polished as I wanted it to be. Well, not anymore! Enjoy the update!

Patch Notes:

• You can now choose the tone of the audio in the settings. It's set to 440Hz by default, which is way nicer on the ears than what was there previously.
• Audio clicking and popping should be 99% fixed. Because I'm generating the audio itself rather than playing back a sound file, you should have a smoother listening experience! The small downside is that CPU usage increased slightly.
• The web build no longer uses SharedArrayBuffers - improving browser compatibility and no longer popping out in a new page.
• Overhauled the desktop builds: Morse Code Simulator now has a proper description, a file icon, and the Windows build has been optimized for size - making it half as big as before. (Linux build still needs to be optimized later)
• Replaced the settings icon with a cleaner one, improved the UI of some parts in the settings menu
• You now listen to the audio while dragging the volume slider in the settings
• Updated the program from Godot 4.0 to Godot 4.4. Aside from general improvements, the program should look nicer when scaled up now and has a new loading screen for the web build.
• Added a donate button in the settings
