Description
Since we can read and (usually) write images tile-by-tile, it would be nice to update ImageConverter? to fully take advantage of this.
It should detect "big images" and for those images perform the conversion one tile at a time, rather than one plane at a time.

(In [b5169baa5916e36aacd511a7deb65f0180716eb1/bioformats.git]) Large-scale refactoring to allow tile-based conversion.
ImageConverter? now converts planes one tile at a time, if the number of
pixels per plane exceeds 224 (4096 x 4096) and the output format is
TIFF or OME-TIFF.
In order to accomplish this, quite a bit of refactoring was necessary.
There are now separate methods to accomplish plane conversion, pixel
scaling, and color model conversion.
Closes #6971.
