[RE-wrenches] Schneider Rapid shutdown with 2023 compliance

[Bradley Bassett]

Note that the MPPT disco RS works only with Schneider charge controllers.
With any other charge controllers you'll need to use Fire Raptors.
Specifically the power line type rsd do not work with classic cc.  I see no
reason why the Schneider units would not meet 2020 or 2023 codes.
