ipa: raspberrypi: Estimate the colour temerature if starting with fixed colour gains
When the AWB is started from "cold" with fixed colour gains, we try to estimate the colour temperature this corresponds to (if a calibrated CT curve was supplied). When fixed colour gains are set after the AWB has been running, we leave the CT estimate alone, as the one we have is probably sensible. This estimated colour is passed out in the metadata for other algorithms - notably ALSC - to use.
