partition_pdf progress bar

[Johnno1011]

I'm looking to implement a progress bar into some code for processing long PDFs. The part of my pdf parsing code that takes the longest is the unstructured_inference partition_pdf method. I've been looking around in the codebase and on this github and online, but I cannot find anywhere examples or discussion about a progress bar that could be implemented for this method.
Has anyone done this or knows how it could be done? Many thanks.
