File splitter property in Go

The File Splitter splits PDFs and Excels into collections of individual pages or sheets.

Historically such splitting was generally done as a pre-processing step with code, but this is now available within Go natively, no code required.

This unlocks a deeper level of page by page or sheet by sheet analysis. For instance, you can turn an Excel file into a collection of sheets, run models over the individual sheets, and then aggregate these answers back up into a summary of summaries.

Since PDFs are split into pages represented by JPEGs, this also unlocks the native multimodal understanding of the latest foundation models, which can power tasks like reading charts or images from pages.
