use Canvas#toBuffer() instead

Drop this lib

chess-image-generator/src/chess-image-generator.js

Line 5 in e885ef1

const Frame = require('canvas-to-buffer');

it will work much faster

Just did some testing on this, and didn't see any performance improvements. It might have been my implementation, but I actually saw a 100ms increase. You still need canvas, since canvas-to-buffer doesn't include tooling for createCanvas or loadImage. The latter could be abstracted away using svgs, but the former will always be needed. eg:

const { createCanvas, loadImage } = require("canvas");
const Frame = require("canvas-to-buffer");

const canvas = createCanvas(this.size, this.size);
// ... all the existing code

// Output
const frame = new Frame(canvas);
return frame.toBuffer();
