feat: Improve virtual mouse speed calculations

Prior to this change, the mouse speed was controlled by an opaque
numeric value, that controlled both the speed and the delay between
updates. This caused a lot of choppy behavior with lower speeds, and the
really low speeds had as little as 1% speed difference between them in
the practical pixels/second speed, while there was effectively a 50%
jump in the speed between speed settings 11 and 12, due to the
hyperbolic relationship between steps. Post that, it was an even 25%
increase in sensitivity for every step.

This change modifies it so that the old Speed option is deprecated, it
is now replaced by the Sensitivity option, which is a direct percentage
scale from 10% to 500%. In addition, there is a CurveFactor option to
let it have fine control when there is little deflection, and move
faster when further away from the center. This also adds an
IsometricMode option which computes the speed as a function of the
cartesian distance from the center (`sqrt(dx^2 + dy^2)`). The default
behavior uses the existing linear speed which controls the speed of the
X and Y axes independently, but now uses the sensitivity and curve
factors to get better behavior. Also, the mouse events are consistently
reported every 10ms. This should make it a lot smoother.

Finally, this change also adds a Deadzone factor, which allows the user
to ignore small changes near the center of the joystick that can cause
mouse drift. This deadzone uses the total distance, so if just the X or
Y axis has moved, it will still allow suppressing any play in the thumb
stick.

 ### Changed
 
 - Migrated CI builds to run in multiple distro containers.
+- Improved virtual mouse motion to use a smoother approach, as well as allow an isometric speed calculation. This change deprecates the old `Mouse.Speed` configuration option and replaces it with a Sensitivity percentage option.
 
 ### Fixed
 - Addressed meson build bugs found in v0.3.3
