[Users] disabling subcycling

[Erik Schnetter]

Setting all refinement factors to 1 is a special case that isn't explicitly
handled by Carpet. Carpet thus still assumes that time interpolation may be
necessary, and requires sufficiently many time levels for the requested
time prolongation order. You can set the time prolongation order to 0
(which corresponds to "copy nearest available data without interpolation"),
which requires only 1 time level.
