Workaround for printf issue

Workaround for printf issue identified in issue nRF24/RF24Gateway#25

Funny stuff going on with the printfs, maybe this should all be changed to use Serial.print(F(

That would only work on Arduino though, right?

It is wierd that the solution is to handle millis() in a separate IF_DEBUG*(). Is it possible that these debug calls happen within an ISR for RF24Gateway?

Yeah, not really a good solution. I'll have to pick this up tomorrow or sometime soon.

I haven't been using RF24Gateway with the interrupts enabled because it needs root.

I asked about the ISR because I think millis() (& micros()) is computed from a different memory partition. In AVR core it is computed from CPU registers. It may be done similarly in other cores that use the unified ArduinoCore-API -- all I could find is a forward declaration in that repo.

The Arduino CI wasn't triggered because there were no changes to the Arduino examples. But, I'm guessing you tested this on the Arduino Nano already. All other CI is happy now, thanks!

Before this gets released, we have to revert the changes in 7a7a854 and put them in a separate branch

Similarly with changes in nRF24/RF24Mesh@b774f03, they should go into a separate branch and removed from master.

Now that nrf_to_nrf is available in the Arduino Lib manager, we could also add that lib as a dependency for these network layers.

After some thought, I think we have a bigger issue here with printf not working. Printing the millis() separately kind of works, but I am guessing its just overflowing data somewhere else because I am getting strange behaviour with debug enabled now.

Yeah, I would like to get this all figured out soon, we are past due for a release of all RF24 libs. Changes reverted, new branches created
