Visible (flashing light) warning when failed to write to SD card

Add a flashing light on failure

[neilh10]

Just a thought, if considering how a field technician (non programmer) without a computer, is using or visiting the site, it might be good to have a clear LED sequence Clearly somebody installing/maintaining the site needs an indication its WORKING or NOT working, and there needs to be general power saving.

Other meaningful LEDs for MAYFLY 1.1
the Switched Power Out - RED led
Network Bee Status - blue Bee Power - white

Some ideas here https://github.com/neilh10/ModularSensors/issues/3

That’s a great idea, we have non programmers maintaining our sites.
