Headers and footers for docx

[SimJeg]

Hi,

MsWordDocumentBackend does not support headers and footers while other packages do (e.g. docx2txt). The docx package allow them to extract quite easily for each document section. Maybe it could be done as follows:

for section in docx_obj.sections:
    handle section.header.paragraphs
    run walk_linear on the section objects
    handle section.footer.paragraphs

Note that it can't be perfect because header and footers might change for even / odd pages and it's not really feasible to get the pagination without rendering the document (see here). But defaulting to the odd pages (as done in section.header and section.footer would be great already).
