El Decko Backend OBS Studio Websocket

OBS Studio websocket based backend for El Decko.

First run

Upon running El Decko the first time with this backend installed it will create an empty default config to connect to your local OBS Studio instance at: $XDG_CONFIG/eldecko/backend/obsws.json.
Please update the generated default credentials with the actual port and password of what is shown inside your OBS Studio Websocket Settings.

Use this backend

In order to use this backend you need to supply the streamdeck.json generated by El Decko Core with the following key_config:

{
    "STREAM_DECK_SERIAL_NUMBER": {
        "brightness": 30,
        "key_config": {
            "0": {
            "backend": "edb_obs_ws",
            "event": "SET_CURRENT_PROGRAM_SCENE",
            "event_parameters": {"name":"S: Desktop"},
            "image_idle": null,
            "image_pressed": null
            }
        }
    }
}

This will configure the very first key (0) to use this plugin (edb_obs_ws) and bind the event SwitchScene to it.
The event will receive the parameter map defined by event_parameters, name defines the name of you scene within OBS Studio.
More supported websocket events will follow.
