    Description

      At the moment, if we call WriteTensor on a strided Tensor, it will write the tensor element by element; this can be optimized by combining multiple consecutive writes together.

      If there are long stretches of contiguous data, this might even be able to take advantage of the multithreaded memory copy we have int the FixedSizeBufferWriter.
