Deal with Pyro4 4.46's REQUIRE_EXPOSE
Deal with Pyro4 4.46's REQUIRE_EXPOSE

In Pyro4 4.46 the REQUIRE_EXPOSE configuration item has been defaulted to True,
meaning that all classes/attributes that are called remotely need to be
explicitly enabled via the @expose decorator. We don't want to impose that in
our code, and thus we turn the flag off when loading dfms.
