Errors indexing Google Takout export as comparison folder

[cosmincc]

Description I'm using gphotos sync in a venv with python 3.8 (came installed as default). It managed to build the google photos index successfully, but when building the local index for the comparison it has errors like these:

/opt/gphotos-sync/lib/python3.8/site-packages/gphotos/LocalFilesMedia.py:174: RuntimeWarning: ASCII tag contains 5 fewer bytes than specified
  result = self.__exif.image_description

Traceback (most recent call last):

ValueError occurred during unpack operation:

7862 is not a valid TiffByteOrder

To Reproduce

1. python3 -m venv gphotos-sync
2. ./gphotos-sync/bin/activate
3. pip3 install gphotos-sync
4. gphotos-sync --album-date-by-first-photo --index-only --compare-folder Takeout/Google\ Photos --progress gphotos

I'm afraid I'm deprecating the comparison feature. Just too hard to maintain and not widely used.
