Improve BuWizz 3.0 communication reliability

[BrickExperimentChannel]

I have a suggestion on how to improve the BuWizz 3.0 communication reliability.

Re-send the last message after 200 ms of inactivity, then re-send it again after 600 ms of inactivity.
I've tested this improves the reliability a little.

It reduces the worst cases, where you cannot stop your Lego vehicle from driving to a wall because the communication is having a 2 second halt.

Also, I noticed that the _sendAttemptsLeft implementation you've done is never used, because the sends always succeed, even when the communication is not working.

My reference implementation in BuWizz3Device::ProcessOutputsAsync

Thanks for the suggestion, I'll check it.
