data: skip invalid tags rather than abort when not recursing (#183)

Commit cdf1e32 fixed a vulnerability by aborting early, however the
problem it addressed was able to occur only when parsing nested
directories.

By aborting early, EXIF metadata from many Samsung devices could
no longer be parsed as these often contain invalid thumbnail
offsets/lengths.

With this change, the vulnerability remains fixed and EXIF metadata
from Samsung devices can be parsed (with invalid tags skipped).
