  \brief nitf_ImageReader_setReadCaching - Enable cached reads

  nitf_ImageReader_setReadCaching enables cached reads. Enabling cached reads
  causes the system to read full blocks of data and then satisfy individual
  read requests from these buffered blocks. A cache of block buffers is
  maintained. This is usually more efficent in terms of reading but requires
  more memory.

  \return None
