fix: denoiseprofile: also show "found match:" instead of the profile name for index 0
denoiseprofile: make it possible to copy the information "this profile was set automatically" across images with different ISO and camera vendor
denoiseprofile: only use a[0] = -1.0 to signal autodetection, and don't use epsilon for comparisons
