feat: add --images support to unstructured-get-json.sh (#3888) E.g., now can run: ```bash # extracts base64 encoded image data for `Table` and `Image` elements $ unstructured-get-json.sh --trace --verbose --images /t/docs/Captur-1317-5_ENG-p5.pdf # also extracts `Title` elements (see screenshot) $ IMAGE_BLOCK_TYPES='"title","table","image"' unstructured-get-json.sh --trace --verbose --images /t/docs/Captur-1317-5_ENG-p5.pdf ``` It was discovered during testing that "narrativetext" does not work, probably due to camel casing of NarrativeText 😬
