BLE keyboard or mouse as input

I’d like an example of how to receive input from an BLE keyboard or mouse as an input device. I see an example file here but it is commented out and mentions that it needs to be updated:

[Adafruit_CircuitPython_BLE/examples/ble_hid_central.py](https://github.com/adafruit/Adafruit_CircuitPython_BLE/blob/master/examples/ble_hid_central.py)

Start with Adafruit_CircuitPython_BLE/examples/ble_hid_central.py, which the issue identifies as a commented-out example needing an update. Determine the existing example's intended BLE HID flow and make it demonstrate receiving input from a BLE keyboard or mouse; done means the example is usable for that purpose.
