Feature request: Switch based on detected display

[rebuhnette]

My setup consists of two MacBooks, one Studio Display and Trackpad/Keyboard.
Trackpad and Keyboard are only used when MacBook is connected to Studio Display (ASD).

Feature request
Detect if external display is connected and automatically connect BT devices based on this information.

1. Detect changes in display connection

2. Check for

• any external display connected (unreliable when using displays in other places)
• check for connected ASD Vendor ID 0x05AC (1452) Product ID 0x1114 (4372) (only for ASD, too generic, not feasible when mutliple ASDs in work environment)
• ASD serial number (only for ASD, SN can be found in system profiler)
• detect other properties like ASD camera ID, Thunderbolt / USB ID (only for ASD)

3. Connect BT devices automatically after ASD was connected via USB-C.
