v3.0.0

It may be a bit of a stretch to call this a major release, but I didn't want to introduce breaking changes for anyone. This now requires at least Node.js 14 (since anything earlier is unsupported), and it's built with TypeScript 4.6.4. The API is identical, though.

I updated all of the dependencies to the most recent versions. This resolves a security vulnerability, but as all of the dependencies are devDependencies (development-time) any vulnerabilities won't impact consumers. This should avoid overly aggressive scans flagging this library, though.
