[Ovmsdev] Branch for-v3.3 network issues

[Michael Balzer]

Craig,

just to be sure: you refitted both your modules with an ESP32 rev 3, 
only difference is, the production module is running "master", sim7600 
module "for-v3.3"?

If so, my conclusions so far would be:

a) we've got a real heap corruption issue that sometimes gets triggered 
by the test. I've had it twice around the same place, i.e. within the 
scheduled event processing. I'll check my code.

b) more important: only ESP32 rev 3 really solves the SPIRAM bug. It's 
not completely solved by the workaround, the workaround just reduces the 
frequency.

Thanks,
Michael
