Including a Llama Parse PDF to Markdown converter

-----------------------------

Extracting data, especially table data, from complex PDFs with tables used to be a challenge. But with the launch of LlamaParse by LlamaIndex, that period is now over.

- The API call works faster than the Python package.

- Chunking the file before parsing improves speeds.

- Currently, around 50 pages seems to be the optimal chunk size.

- Parsing is faster when done in 50-page chunks versus the full file at once, even for say a 100-page report.

- Tested chunk sizes between 25 to 100 pages, with less than 50 or more than 50 pages increasing the conversion time.

- However, all this can change rapidly as LlamaParse is evolving quickly. For example, just a few days back they increased file size limit from 200 to 700 pages.
