exifread.heic.NoParser: hdlr

[honzajavorek]

Using version 3 of exif-py, it crashes when trying to parse a .HEIC photo from an iPhone, e.g. the one I'm attaching zipped here: IMG_4733.HEIC.zip

/Users/honza/Downloads/cindy_test/IMG_5394.HEIC
Traceback (most recent call last):
  File "/Users/honza/Library/Caches/pypoetry/virtualenvs/cindy-WgoVcAt6-py3.11/lib/python3.11/site-packages/exifread/heic.py", line 171, in get_parser
    return defs[box.name]
           ~~~~^^^^^^^^^^
KeyError: 'hdlr'

The above exception was the direct cause of the following exception:

Since this is still an issue as of v 3.0.0, for anyone facing this issue, downgrading to the latest 2.x release solved it for me:

python -m pip install "exifread<3"
