As described in #3381, some clients, perhaps including Adobe PDF Converter, map JPEG images to the invalid `image/jpg` MIME-type. Prior to v1.0.0, `python-pptx` would not load these images, which caused image extraction to fail. Update the `python-pptx` dependency to `v1.0.1` or above to ensure this upstream fix is always available. Fixes: #3381
