Addresses
[#1332](https://github.com/Unstructured-IO/unstructured/issues/1332)
with `unstructured-inference` PR
[#208](https://github.com/Unstructured-IO/unstructured-inference/pull/208).
### Summary
- Add `image_path` to element metadata
- Pass parameters related to extracting images in PDF
- Preserve image elements ignored due to garbage text if
`el.metadata.image_path` is `True`
### Testing


from unstructured.partition.pdf import partition_pdf

f_path = "example-docs/embedded-images.pdf"

# default image output directory
elements = partition_pdf(
    f_path,
    strategy=strategy,
    extract_images_in_pdf=True,
)

# specific image output directory
elements = partition_pdf(
    f_path,
    strategy=strategy,
    extract_images_in_pdf=True,
    image_output_dir_path=<directory path>,
)
