Description

Initialising the mixer causes Pygame to burn one whole CPU on Linux:

https://github.com/pygame/pygame/issues/331

Pygame Zero should initialise the mixer lazily (eg. when sounds are loaded) to avoid suffering performance problems if the mixer is not needed.

Contributor guide

Research direction
Trace where the Pygame mixer is currently initialized in the pgzero codebase and change it to initialize only when a sound is loaded or played.
