Add support for using the nRF52 preprogrammed random MAC address
...
Each nRF52 chip comes preprogrammed with a random static MAC address.
This is the default MAC address that is used if we don't specify one.

Introduces version-specific config & condition BLE lux encoding
...
In the BLE service data payload, one of the reserved bits is now used to
indicate whether or not the ambient lux value is encoded in the packet.
Bit 0 of the first byte is now the `has_lux` bit. If it is set, bytes
16-17 in the service data will contain the ambient lux. If `has_lux` is
not set, bytes 16-17 may not exist (for compatibility with older
firmwares) or may hold meaningless values.
This commit also introduces version-specific configuration in
prst_config.h. Photoresistor config, for example, is only meaninful for
version 1.1.x.

Improvements to photo resistor-based lux estimation
...
- Code now compiles
- Estimation of the photo resistor resistance works
- Lux estimation from the photo resistor resistance needs more work and calibration
- Lux is now encoded in the BLE advertisement payload
