Add audio interaction

[Adam-McDevitt]

Currently the application only interacts with the user's webcam and only displays visuals. Audio-interaction could be added on both sides, if the user has a microphone connected or if their webcam has a microphone built-in.

As a user this would increase my engagement with the application, and allow for longer sessions of interaction.

Possible audio interactions could include:

• Reacting to loud noises (e.g. this could be the new way to wake the application up from sleep mode, rather than waking up on a new detection)
• Reacting to specific words or phrases (requires natural language processing - probably difficult)
• Making noises along with poses (e.g. a growling/mumbling noise when the leer pose-response animation plays, electronic music when the dab animation plays)

Similar to how the webcam is optional, using a microphone should be optional and the user should still be able to run the application in a limited form
