script a patch that removes terminal whitespace

I think a number of base conversions are going to be automated pieces
that clean up the converted CSRD before it is suitable for further
editing. whereas a lot of human changes are going to be bespoke edits of
the "base" CCSRD, creating the CCSRD itself is looking like it's going
to be some machine work to spruce up the Markdown, so I might as well
include those scripts as well
