Fixes progress effect to turn off all LEDs when progress==0

[guru-florida]

Previous Behavior

The first LED would always remain on even if progress==0. M74 P0 essentially has no effect.

Cause

• The polling of the progress state would not change the internal printProgress variable when 0, due to an if p: statement evaluating to false
• The first frame in the pre-rendered progress array [0...100] would still have the first LED set

Fix

• Added an else clause to the if p: to set the internal variable to 0 if klipper progress state is None or 0
• Implicitly added the first pre-rendered frame to be all LEDs off, frames [1..100] are rendered as normal
  • In my case, I have 10 LEDs. P0 will turn all off, P1 will turn the first one on, P11 will turn the second one on, etc.

Is this repo / klipper plugin not actively supported anymore ?

I don't have a lot of time currently for testing, supporting and developing. I hope I will find more time in the next months.
