[Feature] Float angle for motors

[FredrikNoren]

Is your feature request related to a problem? Please describe. It's not possible to measure a motors angle < 1/360 right now; no matter the number of gears you have.

Describe the solution you'd like I'd like Motor.angle to change from returning an int to a float.

Describe alternatives you've considered I tried implementing it in my code but it gets complex with multiple gears

Additional context Changing it to float would also permit better precision for averaging.
