Bug in gsn_code.ncl fix_zero_contour

I've managed to uncover a bug in function fix_zero_contour in gsn_code.ncl, version 5.0.0. In a case where there are missing contour levels, the difference between contour levels can be undefined, causing an if test to fail. I fixed this by adding the following after line 1096:

    if (ismissing(delta_levels)) then
      return(levels)
    end if
