Computing a (smooth) angular head velocity over time

[sfmig]

Is your feature request related to a problem? Please describe.
Right now to compute this one would: compute the polar angle of (user-defined) head vector, and then take the derivative.

But the output is probably noisy, we would need to think a bit more how this would be improved

• slerp maybe? - SM interested in trying
• Adam mentions scipy circular stats
• opendirection may be useful
