Add some F mount lenses

[kmilos]

Address #2193, #2196 and #2214

Not 100% sure for the Tamron string - I followed the pattern of existing Tamrons in the exiv2 Nikon database, but it is included in lensfun under a slightly different name (Canon/exiftool style?) already... @tuxfanx

This situation w/ 3rd party lens identification across different mounts really 👃 💩

Actually, one should drop "AF" from the modern OSD Tamrons, so this might just work out...

@tuxfanx Can you please confirm this will be matched by lensfun now?

for the canon mount, exiv2 outputs the following:
Exif.Photo.LensSpecification Rational 4 35/1 150/1 0/0 0/0
Exif.Photo.LensModel Ascii 41 TAMRON 35-150mm F/2.8-4.0 Di VC OSD A043
Exif.Photo.LensSerialNumber Ascii 11 0000000000
Exif.Image.LensInfo Rational 4 35/1 150/1 0/0 0/0
you can find some raw pictures taken with the canon mount lens here

In my opinion, the "AF" does not belong in the model designation because Tamron does not use the "AF" either. If AF is used, it should also be included in the manufacturer's model number.
When using the "AF", 2 separate entries would also have to be listed in the Lensfun DB because of the different canon model designation.

"35-150mm F/2.8-4 Di VC OSD" would work, but is it necessary that the entry for Nikon is different from the entry for Canon?

Thanks for checking.

One could ask the opposite just as well. It's all a bit arbitrary, isn't it?

I'd prefer to keep the Nikon (or any other vendor) database scheme self-consistent (how/why we got to different naming schemes is beyond me). I can also happily remove the Tamron from this PR and let someone else handle it, or just leave users put whatever string they prefer in their ~/.exiv2 config file.
