To support the bayesian AWB algorithm in libtuning, the necessary data
needs to be collected and written to the tuning file.
Extend libtuning to calculate and output that additional data.
Prior probabilities and AwbModes are manually specified and not
calculated in the tuning process. Add sample values from the RaspberryPi
tuning files to the example config file.
