RFC for first three patches and v3 for gstreamer mappings.

Mainly the first 3 patches, adjusts ColorSpace::Srgb to define
a sRGB colorspace space. It also accompanied with a colorspace
adjustment API if sRGB is used with YUV. More such adjustments
can be built on top using the ColorSpace::adjust(StreamConfiguration)
API.

Rishikesh Donadkar (1):
  gstreamer: Provide colorimetry <> ColorSpace mappings

Umang Jain (3):
  libcamera: colorspace: Rectify ColorSpace::Srgb preset
  libcamera: colorspace: Adjust colorspace of YUV streams
  tests: stream: Add a colorspace adjustment test

anybody interested to review the series? Perhaps David, Laurent based on 
the previous discussions we had?

Thank you!
