hdf5tojson fails for comp_complex.h5

[jreadey]

This file: data/hdf5/comp_complex contains a dataset with a type that it doesn't parse.

Two wrong conversions:

• Committed datatype /cmp3

  h5dump says:

   DATATYPE "cmp3" H5T_COMPOUND {
    H5T_ARRAY { [2] H5T_COMPOUND {
       H5T_COMPOUND {
          H5T_STD_I16LE "i";
          H5T_STD_I32LE "j";
       } "x";
       H5T_ARRAY { [2] H5T_IEEE_F64LE } "y";
    } } "yy";
  }

  NumPy dtype is:

  dtype([('yy', [('x', {'names':['i','j'], 'formats':['<i2','<i4'], 'offsets':[0,4], 'itemsize':8}), ('y', '<f8', (2,))], (2,))])

  h5tojson says:
