Is your feature request related to a problem? Please describe.

Although OpenDTU is quite stable, it happens from time to time (OTA updates) that the whole system gets stuck. This requires physical access to the hardware to initiate a power cycle.

Describe the solution you'd like

Enabling a simple Task Watchdog Timer (TWDT) could be a solution.

Describe alternatives you've considered

For OTA updates we have ongoing discussion in #319 though this would require safeboot and two OTA app images app0 and app1 as far as I understand the Tasmota approach being suggested for OpenDTU too. This may not fit on the ESP32!
