      Given an element which has no lists and multiple types, read the
      corresponding data, by loading all the data as float64 and converting
      the relevant parts later.
  
      For example, given
  
          element vertex 8
          property float x
          property float y
          property float z
          property uchar red
          property uchar green
          property uchar blue
  
      the output will have two arrays, the first containing (x,y,z)
      and the second (red,green,blue).
  
      Args:
          f: file-like object being read.
          definition: The element object which describes what we are reading.
  
      Returns:
          List of 2D numpy arrays corresponding to the data.
