Automated vial capper/decapper RS485 Python API implementation

[sgbaird]

At one point, I was able to verify that I could connected the RS485 to computer via USB, use one of their desktop apps, and control the state of one of the grippers (sort of a dummy check).

For a while, the plan has been to write a custom RS485 protocol that's written in Python or MicroPython using the https://www.waveshare.com/wiki/Pico-2CH-RS485. This seemed favorable over trying to hack the internals of the programmable logic circuit (PLC) or messing around with the touchscreen interface. Instead, just directly send RS485 commands with this module.

https://youtube.com/shorts/jQLtg0luPNc captures the need pretty well.
