Add mobile device (smartphone) support. #92

The default camera app in both iOS and Android triggers the shutter when the 'volume up' key is sent.

This requires:

building a BLE server
- with the mobile device, the connection orientation is reversed, the ESP32 is the peripheral whilst the mobile is the central
advertising the right services (HID, etc)
pairing with the mobile as a keyboard
wiring the shutter release to send 'volume up'
bending the workflows of 'normal' cameras and mobiles to be similar

During development, I discovered the underlying NimBLE-Arduino library doesn't support querying the central device for its device name. I would rather not hack the library to support this, thus for now, the smartphone is identified by its bluetooth hardware address.
