7378a378 - enhancement: allow setting image block crop padding parameter (#2415)

enhancement: allow setting image block crop padding parameter (#2415) Closes #2320 . ### Summary In certain circumstances, adjusting the image block crop padding can improve image block extraction by preventing extracted image blocks from being clipped. ### Testing - PDF: [LM339-D_2-2.pdf](https://github.com/Unstructured-IO/unstructured/files/13968952/LM339-D_2-2.pdf) - Set two environment variables `EXTRACT_IMAGE_BLOCK_CROP_HORIZONTAL_PAD` and `EXTRACT_IMAGE_BLOCK_CROP_VERTICAL_PAD` (e.g. `EXTRACT_IMAGE_BLOCK_CROP_HORIZONTAL_PAD = 40`, `EXTRACT_IMAGE_BLOCK_CROP_VERTICAL_PAD = 20` ``` elements = partition_pdf( filename="LM339-D_2-2.pdf", extract_image_block_types=["image"], ) ```
