Could cause hangs on the way into sleep (and enormous power consumption).
Instead of checking for rx packet length (which only changes at completion)
check if we've received preamble bits but haven't yet received a completed
packet interrupt.

bogus wakes on TBEAMS because the USB->SERIAL chip pulls the RX input
to ground. This feature is no longer needed because in !isRouter
nodes we force the node to never sleep anyways when on USB power.
// this doesn't work on TBEAMs when the USB is depowered (causes bogus interrupts)
// So we disable this "wake on serial" feature - because now when a TBEAM (only) has power connected it
// never tries to go to sleep if the user is using the API
// gpio_wakeup_enable((gpio_num_t)SERIAL0_RX_GPIO, GPIO_INTR_LOW_LEVEL);
