ENH: use cellPoint interpolation directly for surfaceFieldValue (#1212)

Browse Source 
- prior to sampledSurface supporting different interpolation schemes a
  workaround means was used to simulate cellPoint -> face
  interpolation, with averaging of vertex interpolation.

  We instead now use cellPoint interpolation directly for the face
  values when 'interpolate=true'.
