Restrict max size per document

Uses the new `maximum_size_per_doc` param to the ALExhibits
object to limit the size of individual documents.

In order to attempt to account for the OCR'd layer on the PDF (which
is added after the user uploads their files), it makes the limit stricter
by 1 MB. Might not be enough, but it gets more difficult when the document
that is upload isn't the exact same one that we submit.

Depends on SuffolkLITLab/docassemble-AssemblyLine#1002.
