feat(makernote/nikon): implement Nikon MakerNote parser (#27)

Adds support for Nikon Type 1 and Type 3 MakerNote formats:

Type 1 (older cameras like D1, D100):
- 8-byte header: 'Nikon\x00\x01\x00'
- Absolute offsets (relative to EXIF TIFF header)
- Inherits byte order from parent

Type 3 (modern cameras like D3, D700, Z series):
- 10-byte header + embedded TIFF header
- Relative offsets (to MakerNote start)
- Own byte order from embedded TIFF

Encrypted tags (LensData 0x0098, FlashInfo 0x00A8) are skipped.
