CFclient can't update deck when multiple are attached

[knmcguire]

In this discussion somebody encountered that the lighthouse deck's firmware does not get updated if any other deck is attached: https://github.com/orgs/bitcraze/discussions/96

This also occurs with the AIdeck if a flowdeck or any other deck is attached.

Platform: Windows 11

How to reproduce:

1. Have a Crazyflie with a lighthouse deck or AIdeck, and attach another deck to it as well (which is compatible).
2. Go the the cfclient, go to Connect >Bootloader>flash the latest release (with warmboot)

Result:
The NRF and STM get reflashed but the to be updated deck is skipped.

What I would expect:
Either that the deck is updated without problems, or that there is at least a warning like: 'Multiple decks detected, Can't update'

Can not reproduce

This problem still exists. I get if from time to time, but it is a bit random.
I got it with a Lighthouse deck (with outdated FPGA binary) and a LED ring deck. Curiously enough it works sometimes, but not always.

I have the update problem also frequently (usd + aideck). The main problem I have is that there seems that there is no proper error checking: if the 1wire reports the aideck works, but the UART connection doesn't work for some reason, there is no message. Similarly, when updating the firmware and there is some sort of error, there is no report on that at the end.

Thanks for the input @whoenig !

This is a weird issue that lacks in reproducibility but it comes back every once in a while. it needs more investigation.

There seems to be a number of problems here working together. PRs #664 and bitcraze/crazyflie-lib-python#398 hopefully fixes them.

Tested with LED-ring + AI-deck + LH-deck
