Add missing exif date from filename

fix_missing_exif.py

# small script to add exif date tags to photos that are missing them
# assumes the date is in the filename in the format: <something>-DATE-anythingelse.<jpg|png|etc>
# and that the date can be parsed by dateutil.parser

# dependencies
# pip install exif, python-dateutil
