* fix: extract page breaks from .docx files
Context: Currently, DOCXToDocument does not extract page breaks from
word documents. This makes it impossible to do things like split by page
or get correct page number metadata after using something like
DocumentSplitter. For example, if you split by word, the 'page_number'
metadata field will be 1 for all documents.
Solution: Added a method to DOCXToDocument that extracts page breaks
from word documents as '\f' characters so that they are recognized by
DocumentSplitter.
Caveat: Due to the way the python-docx library is set up, you can only
accurately determine the location of the first page break for a given
paragraph. In the rare case that a paragraph contains more than one page
break (which means it is an extremely long paragraph spanning multiple
pages), the 2nd, 3rd, etc. page break locations are not known. To sort
of fix this, I just appended the page break characters to the end of
the paragraph text to keep the overall page number values for the
document consistent.
