ENH: bounding box clipping for ensightWrite function object (issue #973)

- for larger problems with a smaller region of interest, can apply a
  bounding to limit the size of the ensight geometry and fields created.

  Since the implementation uses a fvMeshSubset, there is an additional
  per-process memory overhead.

  A high output frequency should be avoided with moving meshes, since
  this indirectly forces a frequent update of the submesh.
