ART-cli verbose flag -V is too verbose

The ART-cli prints a lot of useful details and diagnostics about profiles and colour handling, most of which fits on 1-2 pages of the console.

However, it also prints about 30 pages of camera constant loading messages, at least one line per camera in the various databases:

...
Add camera constants for "SONY XPERIA 1 II TELEPHOTO CAMERA"
Add camera constants for "SONY XPERIA 1 II ULTRA WIDE-ANGLE CAMERA"
Add camera constants for "SONY XPERIA 1 II WIDE-ANGLE CAMERA"
...

It would be great to have a way to get just the good stuff in verbose mode. E.g. having two verbose modes -V for verbose and -VV for extra verbose.

This is the information I’d like to get in a shorter, but still verbose, mode:

Profile loading and any missing profiles
dcraw diagnostics
Output profile (especially if it’s missing or fails in some way)

E.g. of useful verbose output:

Settings directory (rtdir) = /home/redact/.config/ART
Cache directory (cacheBaseDir) = /home/redact/.cache/ART
Default profile for raw images "Dynamic" found
Default profile for non-raw images "Neutral" found
