Migration to v4

With v4, this library introduces a few small but breaking changes, so migration from v3 should be deadly easy.

New exports

Default export was renamed to Canvg

v3

import Canvg, { presets } from 'canvg';

v4

import { Canvg, presets } from 'canvg';

TypeScript 4

Starting from canvg v4, you should use TypeScript 4.
