Implement Numba (JIT Compiling) natively into pynecone

[Cheesy-Brik]

Since you're most likely recalling event functions a ton, might as well take advantage of some JIT for performance gains (especially in large apps)

[FHU-yezi]

Currently our bottle neck of performance is network lag and front-end repaint.

Numba wouldn't help here, since we don't have any heavy number crunching code (or indeed any code that would benefit from vectorization or SIMD).
