Field of view over the long image dimension, in degrees (Exif.pm FOV).
Quirk kept deliberately: ExifTool divides by the LITERAL 3.14159, not
Math.PI. The difference is below the "%.1f deg" rounding threshold in most
cases but not all — use the same constant to stay byte-identical.
(FocusDistance correction ignored: we don't parse a FocusDistance composite.)
