[Feature] Ability to make small/slow movements with run in place locomotion

[dantman]

I tried moving my arms slowly using the run in place locomotion, but as soon as they move just far/fast enough I lurch forward at full speed for a moment making fine movements impossible.

It feels as if run in place is on/off digital movement. Even though documentation says it is variable and trackpad based movement can do slow movement.

A good arm swinger implementation for comparison is the one in Hot Dogs Horseshoes & Hand Grenades.
