Subject: [PATCH] Attempting to fix .else

Hi! We at tretton37 found a bug in the .else branch. Comparing https://github.com/becdetat/Simplicity/blob/master/src/Simplicity/PatternMatching.cs I guess I've made the right fix. But would need some tests and maybe a mention in the docs how multiple .else should work.

I guess this is a breaking change, so 4.x? SemVer grumble grumble ^_^
