Reset Center On Head Tilt

[dlktdr]

Idea from another head tracker project. https://cdn.discordapp.com/attachments/827622724565467199/901051561508225044/unknown.png

Add the ability to reset center by tilting your head full one direction and full the other within a certain time will reset the pan center only.

Or possibly roll left/right.. delay 1-2 seconds, and that is the new center on all axis.
