v3.0.0-beta.1

Changelog

This is a beta release of 3.0. The breaking change is that we now require an external library which is installed by composer. Before release we'll need to update the documentation about how to do a stand-alone install (see #160) and ideally add support for PHP 7.4 (see #165).
