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.
