[PF] Elementalist NPCs level 1-20

Hello, everyone!

Back in 3.5, there was a series of tables in the Player's Handbook 2 with examples of classes from level 1-20. I always thought it was a great idea, and it's been bouncing around in my brain for a while now to do something similar for some Pathfinder 1E classes.

With that in mind, here is [a table for a Spheres of Power Elementalist from levels 1-20](https://docs.google.com/spreadsheets/d/1cUoVNtOpVx4j22b1WziRxe2UXJAduLwGX-VuUrfrmho/edit?usp=sharing) and a [discussion document](https://docs.google.com/document/d/1A2UbP-UAmzIFQW4z0UQRid7pMFaZjh6rV1Z0A3uwU24/edit?usp=sharing).

I've been saying [since I first read the Elementalist](https://docs.google.com/document/d/1tO_54JKqgF2k7GN06-eSFrgWneugh6DEor-TnSzN4JM/edit?usp=sharing) that it's a great, simple class to run as a GM.

I just mashed out all this on a keyboard today, so I'm sure there's terrible formatting, blatant mistakes, and poorly-explained parts. I'll try to tweak it over time, but this should be good enough for someone to throw an Elementalist at a party of any level immediately.

Thanks, Nova
