Sending api packet to SX DM with addr64 == 0 kills all communication

Wow, just wow. For all you out there, I just wasted 3 days of my life. My dest addr64 variable was initialized to zero…kinda like you’d expect…but if you accidentally try and send anything to that address (at least in DM mode), the SX will go dead forever until reset/reboot!!! Like, a professional solution would give you back a TX status saying there is no 0 on the network, or even timeout after a few seconds, but NO, the SX just f’ing dies, no serial communication, no error, nothing! Buyer beware…

I will note that XCTU can still see the radio remotely from another radio just fine, but all serial communication with the local processor/uart will henceforth cease.

No need for a reply unless newer f/w is released with a fix, this is just for anyone else out there who may likely experience the same thing, since we pretty much all use zero as our initializer for variables in C…
