Add SDR and HDR DCDM built-in displays, which are in the set of Output Transforms recommended by ACES 2.

Improve the Rec.2100 surround algorithm used for the Rec.2100-HLG OOTF and EOTF:

  • Fix an issue with the inverse
  • Mirror the result around the origin for negative values

The only other display I see missing is the Display P3 / Gamma 2.2 variant, but maybe we already decided not to include. LGTM in any case!
