Couldn't find any function like this on the internet so I made it :)

It will properly detect an event for any scramble given.
Only issue is since 3x3 and OH scrambles are generated the same, you obviously can't tell them apart.
Also be careful with multiple spaces between moves, though it should still work.

Super interesting function and case structure.
5BLD scrambles will have 3Rw or 3Uw in the end.

MBLD is a standalone event, it does not need differentiation.
