Configure whether esptool.py should reset the ESP32 before flashing.
Automatic resetting depends on the RTS & DTR signals being
wired from the serial port to the ESP32. Most USB development
boards do this internally.
The "Reset with ESP32R0 Windows workaround" option works
around an automatic reset bug in hardware, when using Windows
with some development boards. This fix only works if you're
using a silicon revision 0 ESP32.
