LR-EDIT-COLOR-MIXER-BW + LR-FILT-TYPE: Auto B&W mix, HDR / panorama type filters

Browse Source 
- develop.autoBwMix (B&W Mixer → Auto): each hue band's colourful pixels are pushed away from
  the image's mean lightness (light bands brighter, dark ones darker; bands with almost no
  colour untouched), clamped to ±60; switches to B&W; one undo step.
- library.filter {merged: hdr | panorama | hdrPanorama | any}: Photo Merge results recognised
  by the "-HDR" / "-Pano" / "-HDR-Pano" names merges write; filter bar type picker lists HDR,
  Panoramas, HDR Panoramas.
