Added motor and current saturation to the led status bar

Following up on this suggestion here: #44 (comment)

A couple things to align on before this is ready to merge:

• right now DUTY = orange, MOTOR I = magenta, BATTERY I = green - let me know what you'd prefer
• currently when the battery is low the last LED pulses every second - do we want this faster/slower?
• should I split out the battery blinking into a separate commit + feature: / leave it as is / update the current commit message + trailer? done in On low battery pulse a single red led #84
• I renamed status_duty_blend -> status_blend, and also duty_threshold -> status_threshold, hope that's alright renamed to status.motor_utilization_threshold

Thanks for this.

I was actually just recently thinking I should get to add the last led blinking when battery empty. Yes please definitely do that as a separate commit, it's independent from the motor utilization change. Could even go into a separate PR.

I'll have to find some time to do a full review, how determined are you to get this into 1.3? Should be possible... At first glance the code looks reasonable...

I'm not fussed, if I want these features I can just put them on my board myself.

Sounds good, I'll remove from this PR and create a new one.
