Add Sker Ritual

If you are adding or modifying an Auto Splitter, please fill out this checklist:

• My Auto Splitter does not contain any malicious functionality and I'm entirely responsible for any damages myself. (Any kind of abuse in an Auto Splitter will result in an immediate ban.)
• I am not replacing an existing Auto Splitter by a different author, or I have received permission from the author to replace the existing Auto Splitter.
• The Auto Splitter has an open source license that allows anyone to fork and host it.

(!) I have used a custom patch of asl-help. The reason being this issue: just-ero/asl-help#13

I have a patch that works for this game, but will definitely break other games. So, I can use that for specifically this game while a better patch is found. I don't know enough about how to introspect Unity internals to figure out what is actually happening and fix upstream.
