add closure report templates to validphys examples

Created by: wilsonmr

This closure test should add the two agreed closure report templates to validphys examples.

During the creation of reports we saw that a few of the providers might need some modification to work better with the reports, namely using 'fakepdf' instead of 't0' pdf from the closure fit.

Also should address why I was having issues creating plot fancy style plots which could also go in the report (see #302 (closed))
