Update Math Evaluator Version

[MLGPenguin]

Rewrote the math evaluator to generate and evaluate mathematical tokens as to circumvent the pitfalls of using regex as I was doing previously.

Now more stable, handles more complex queries and supports ln() as per request @cirosanchez @atomisadev

you didnt need to add ln, it was a joke i feel bad now

It's okay lol that part was easy, the rewrite was to support more complex stuff
