d8aea1d4ef 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.

e32803d44d 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

dcd0fc4ae1 Calculate photoresistor and some other fixes (#3) 
prst_adc_photo_read() now calculates the photo resistor and return it as the lux level.
Added debug logging and fixed some syntax errors.

c9b05859e4 First draft for Photoresistor 
the code now should setup and use the photoresistor and read it's value by the adc.
the returned value is 0 just as a place holder until the correct values are measured.

fb07a1244c PWM start/stop in RTC callback. 
I initially tried calling prst_pwm_init() in main(), and just using start/stop in
the callback, but that led to a weird behavior in the PWM output. It was set to
high after the end of the callback.

Callnig uninit/re-calling init() inside the RTC callback fixed, but more investigation
is required.
