Speedrun configs update (1.43.1)

Okay, so speedrun kit has been deleted, due to it being incredibly outdated and very hard to maintain...

And it came back!

• Updated randamu.asl to support latest version of Randamu.
• All split files now use latest version's app icon.
• Layout files now have unified data components, so they provide the same info, and no longer have Auto Splitter by default, since I couldn't figure out how to make the layout link to script in its folder.
