ENH: Lightpath "lite" (CLI output, minimal widget)

[tangkong]

Expected Behavior

This was requested a few times, but it might be convenient to have a more lightweight lightpath interface.

Current Behavior

Currently you either have to access the lightpath python interface or the full GUI.

Possible Solution

Two ideas come to mind.

1. a more fleshed out cli interface that can return the inserted / removed / impediment devices for single destinations

   • lightpath --hutches <HUTCH> blocking
   • lightpath --hutches <HUTCH> impediment

2. a widget that contains a single lightrow widget (device icon, name, blocking color), without any of the filtering or typhos-ing bits.
