cache TailwindMerge instance

[thedumbtechguy]

This is a resubmission of #94

---

TailwindMerge operates a cache and undertakes a lot of operations that require that an instance be reused rather than constantly instantiating one.

I added a simple benchmark

@thedumbtechguy you just need to fix the standard.rb! 😄

[thedumbtechguy]

Oh lol. Sure thing.

[cirdes]

Awesome!!!
