Wait for altimeter when using packet mode. Instead of quicly
timing out when trying to initialize a packet mode
configuration connection, AltosUI now waits indefinitely for
the remote device to appear, providing a cancel button should
the user get bored. This is necessary as the TeleMini can only
be placed in "Idle" mode if AltosUI is polling it.
