Add optional low pass audio filter #72

Closed jdgleaver closed 3 years ago

The Atari 2600's TIA chip produces rather 'harsh' sounding audio. This PR adds an optional low pass filter which softens and improves the generated output. The filter can be configured via new Audio Filter and Audio Filter Level options.
