v7.0.22

• HDR PNG carries the capture's ICC profile (#448). 7.0.15 wrote the cICP tag only;
  viewers that go by the ICC profile (and the reporter's) showed the image as SDR. Sony's
  "ScreenCapturePQ" profile is now read out of the .jxr and embedded as iCCP in both HDR
  variants, with cICP beside it in the tagged one.
