Add a flag to wait for serial port (Feature request)

[mikhail-m1]

It would be nice to have a flag (something like --wait) to wait for serial port to appear in the system. I can make a PR if you are ready to merge it.

Hi! Do you mind elaborating on your use case for this flag? I guess you want to run the command and then plug the board? Will the command ever timeout?

[mikhail-m1]

Yes, I want for the tool to monitor devices and connect as soon as device is plugged in. I don't think I need a timeout, I can always press CTRL+C. But I don't see why not to add it.
