tags: exif: Fix bug in inner ifd parsing
...
Do not use the result of inner ifd's parsing to increment
the current tag index. The reasons are:
1) The function returns a boolean.
2) The inner ifd's tags are in a separate table, so they shouldn't
interfere with its parent ifd table parsing.

tag: Adds basic exif tags support

Adds exif helper lib functions to parse exif buffers from/to

exif is embedded in jpeg and (obviously) in tiff.
