Add support for Adobe RGB 1998 as a selectable color space for VFB display and render output

I have already discussed the issue of saving PNG files in the Adobe RGB 1998 color space with technical support and on the forum, but I have not found any way to achieve this. Corona performs its rendering calculations in Wide Gamut RGB, but subsequently clamps the colors to the sRGB color gamut.

Monitors are now quite commonly capable of displaying Adobe RGB 1998. For example, my client explicitly requires this color profile for visualizations. It would therefore be great to be able to save visualizations in the Adobe RGB 1998 color profile and not lose as much color information as when saving to sRGB.

I would like to ask for the possibility to choose the preferred color space into which the render is saved, as well as the color space used for display on the monitor (for example, Adobe RGB 1998 or sRGB).
