Gabrielerusso/vesc_pas_lisp_3 ? reverse-engineered prompt

Build me a VESC LISP script for an e bike that uses a 3 wire PAS sensor, a throttle, and an optional brake input.

I want it to behave like a normal EU compliant pedal assist setup, so motor assist only works while I am pedaling, throttle only gives limited walk assist when the bike is moving very slowly, and the brake input should cut power immediately if it is connected. The PAS signal should come in on the PPM pin, the throttle on ADC1, and the brake on ADC2.

Please make it easy to upload and use in VESC Tool, and include sensible default behavior so I can test it right away. If you need to check current VESC scripting details, look them up online. Keep the script focused on safe, practical pedal assist behavior for a cargo bike.
