I rebuilt the RGBScan profile so there is no gamma shift

[thetalkingdrum]

I rebuilt the RGBscan profile, so it maches TRC g2.2 that Negpy seems to use at that stage in the pipeline.
It had a mismatch in TRC (uses srgb trc) causing a lift in the toe area and slightly washed out look when using the profile as input.

With the rebuilt profile there is no gamma shift when switching input from "none" to RGBscan, but the color transform is the same.
It could replace the current version. I wasn't sure about the right section to post this, so here it is.

Thanks! I will update it for next release
