blending: revamp blend operators to ease handling of color space specific code
exif: always try to use Exiv2's lens detection for Olympus

Example:
Exif.OlympusEq.LensType                      Byte        6  Olympus Zuiko Digital ED 14-42mm F3.5-5.6
Exif.OlympusEq.LensModel                     Ascii      32  OLYMPUS 14-42mm Lens

The lensfun-0.3.0 database has been cleaned up and has proper matches to LensType
The lensfun-0.2.8 database has something that looks like LensModel, but not quite.

LensModel is very ambiguous in any case and thus probably shouldn't be used in any case.

Particularly when taking in account metadata is read at import time, it makes a lot of sense
to use the most "future-proof" option, which will be LensType.
