Michael Mayer 41b252d820 People: Add unofficial env variables to tweak face matching #1587 #2182
Adds two unofficial env variables so advanced users can experiment:

1. PHOTOPRISM_FACE_KIDS_DIST=0.6950 (range: 0.1-1.5, -1 to disable)
2. PHOTOPRISM_FACE_IGNORE_DIST=0.86 (range: 0.1-1.5, -1 to disable)
