Maolan 0.2.4

Hello,

Most of my work for the latest https://maolan.rs version was to make 
Windows binary more stable. Besides that, UI was unified, Live Session 
(somewhat resembling Ableton Live) was implemented and documentation was 
added. Future work will be focused on implementing plugins and Maolan 
Generate - set of AI models targeted at generating audio and/or MIDI 
from prompt.

On a more technical side, I'm really excited I can say I learned in 
implemented lockless structures in the engine which removed a lot of my 
"hacks" that were needed for real-time processing. Maolan engine is now 
truly lockless without structures that were causing undefined behavior 
in edge cases, which was a nightmare to debug. MUCH cleaner code now!

On package side, download page offers Windows setup file and AppImage, 
besides native packages for Debian, Ubuntu and Fedora. I'm hoping that 
AppImage will allow people to test this program on distributions that 
don't have native Maolan packages.

As always, feedback, PRs and suggestions are welcome!

Regards,
meka
