Add typescript definitions

[joeyfigaro]

I took a first pass at running everything here through tsc and this was the result:

export function generateParticles({ count, height, margin, seed, width, }: {
    count: any;
    height: any;
    margin?: number;
    seed: any;
    width: any;
}): {
    x: number;
    y: number;
    vx: number;
    vy: number;
    line: any[];
}[];

export function moveParticle({ amplitude, damping, frequency, lengthOfStep, particle, }: {
    amplitude: any;
    damping: any;
    frequency: any;
    lengthOfStep: any;
    particle: any;
}): void;

export function generateField({ amplitude, count, damping, height, margin, particles: suppliedParticles, scale, seed, width, }?: {
    amplitude?: number;
    count?: number;
    damping?: number;
    height: any;
    margin?: number;
    particles: any;
    scale?: number;
    seed: any;
    width: any;
}): any;

Looks like the return type for generateField is wrong–are you open to adding type defs to the distributed library?

@romellogoodman if you are open to having them added, I'd be happy to open a PR with config, types, and a naive pass at supporting scripts for your publishing process.

Hey, so im not looking to add typescript to this project at the moment. Feel free to fork though!
