Increase possible Regex complexity for AutoMod

Having Regex for AutoMod is amazing! However, it appears to be incredibly limited at the Moment. I have written Regex to catch variations of multiple slurs and NSFW words, but I can't use any of them in AutoMod because it says "Regular expression compile size exceeded limit". 

I'm not entirely sure where the limitation is, but allowing more complex Regex would be very very helpful.

(As extra information: the shortest Regex of the ones I tried is 22 characters long)
