• original naïve PR to root repo: ability to only run specified Stream Decks instead of all attached decks StreamController/StreamController#227
• work is in branch https://github.com/violet4/StreamController/tree/only_attach_specified_decks

command line arguments:

• --list all detected attached stream decks and exit. output includes "paths" to the stream decks so they can be differentiated.
• --paths (nargs='+') to specify that this instance of StreamController should only interact with those specified on the command line.

issues to address:

• if a StreamDeck instance is already running and --list, it pops up the running instance instead of listing decks.
• a deck is attached to USB while StreamController is already running with --paths. the newly attached deck wasn't specified in --paths, but StreamController now takes over control of it from any other software that might want to try to interact with that deck.

Possible feature enhancement (address this later):

• Support this in in-app settings so it persists across boots and doesn't need to be manually specified on the command line every time.
