[Feature Request] Allow per-button host info, or multiple hosts #14

This might be a niche use case, but I was hoping there would be a way to support multiple different OBS hosts with this plugin. I have a two PC setup; I like to start stream/recording on my secondary PC via obs-ndi, but manage all the audio/scenes/etc. on my primary PC. Switching host on one button switches it for all. I can work around this by using buttons for run commands using obs-cli, but this has the slight drawback of not having buttons whose state changes based on OBS's state.
