ipa: raspberrypi: Add a "scientific" tuning for the IMX477
Add a tuning file for the IMX477 more suited to scientific applications. The key differences from the original tuning file are: - Disable ALSC block completely - Pure rec709 gamma curve, and no contrast enhance - New CT curve and CCMs based on the illumination spectrum of a black body radiator up to about 3600 K and the CIE illuminant D for higher color temperatures. Further details on the changes can be found at: https://forums.raspberrypi.com/viewtopic.php?t=343449 All credit for these changes go to Dr. Rolf Henkel.
