E220-Remote-Switch updated 07/29/2024.

Found an issue with KY002S, Bi-Stable MOSFET Switch where every push of the ESP32 reset button caused the KY002S switch to toggle states. Getting the on/off battery power out of sequence. 07/29/2024 fixes this issue.

Issue was fixed by reading the KY002S Voltage Out pin; then writing the desired trigger state to the KY002S, TRG pin. This was placed in setup; insuring correct trigger state on boot or reset.
