/**
* @class vtkOMETIFFReader
* @brief reader for OME TIFF files
*
* vtkOMETIFFReader supports reading OME-TIFF files. These are TIFF files with
* OME meta-data that helps interpret the contents of the TIFF.
*
* The OME-TIFF specification is available here:
* https://docs.openmicroscopy.org/ome-model/5.6.3/ome-tiff/specification.html#ome-tiff-specification
*
* The current implementation only supports single-file, multi-page TIFF. It
* will not read multi-file OME-TIFF files correctly.
*
* Unlike most image readers, this reader does not support arbitrary sub-extent
* requests. This is because the splicing of the `z`, `t`, and `c` planes can make it
* tricky to read sub-extents in `z` for certain dimension orders. This reader
* supports piece-request instead and satisfies such request by splitting the
* `XY` plane into requested number of pieces.
*
* The reader lets the superclass read the whole TIFF volume and then splice it
* up into channels, timesteps, and z-planes. The parts are then cached
* internally so that subsequent timestep requests can be served without
* re-reading the file.
