Add new parameters derivatives_zero_y and derivatives_zero_z in order to
ecplictly setting any derivatives in the y- and/or z-direction to zero
when simulating 1- or 2-D problems with a 3D code. This avoids issues with
errors at roundoff level in the y- and z-directions. Should be used with care
and together with the parameter check_grid_sizes to avoid complaints about
too small grids in the y- and z-directions.
Has only been tested in a few cases. If problems are caused by this commit,
please report them immediately.
