Uses the example model from PR OPM/opm-tests#1279 in which the
defining expression of one UDQ is exactly 128 characters long. This
expression will overflow the character limit if we insert any new
characters like blanks or quotes.
In particular, output the per-cell oil, gas, and water fluid in
place vectors using compatible array names and surface condition
unit conversion tags.
While here, also relax certain parallel and restart case regression
test tolerances to make the tests pass once we generate the arrays.
