Ignoring headers and footers with PyPDFLoader

[olegshirokikh]

Using PyPDFLoader or DirectoryLoader with loader_cls=PyPDFLoader, is there any way to ignore headers and/or footers on PDF pages?

PyPDF module itself supports some callback mechanism for this kind of task, but not sure if it's possible to integrate with Langchain's APIs

Here's the standard usage example from Langchain docs.
