This release only removes the "hot path" after finishing TX.
It was an attempt to eliminate "Sent" but not "Heard X repeats" messages.
I re-did the math, we don't need to stay in full RX after TX for any reason, immediately back to duty cycling is fine until someone starts to use SF7/BW500.
Getting back to duty cycling is in the ms range, no preamble can be missed, so "Sent" but not "Heard" packets are seems to be truly RF collision/repeater listening to other packets etc.
