Add lens info for NEF, ARW, RW2 & ORF

[StefanOltmann]

The formats NEF, ARW, RW2 & ORF are missing the lens information, because it's not written to standard EXIF fields and must be constructed from MakerNote data.

These documentations describe how to do so:

• https://exiftool.org/TagNames/Nikon.html
• https://exiftool.org/TagNames/Sony.html
• https://exiftool.org/TagNames/Panasonic.html
• https://exiftool.org/TagNames/Olympus.html

This document provides an overview: https://exiftool.org/makernote_types.html

metadata-extractor has logic to identify the kind of MakerNote that is present: https://github.com/drewnoakes/metadata-extractor/blob/67dfddd72e3cfbb7bf802a672eacc70b42fba601/Source/com/drew/metadata/exif/ExifTiffHandler.java#L426
