Moved premultiply and demultiply out of image_32 and other parts of the code. The image_data object is now responsible for keeping track of its own premultiplied_alpha status. Created a new utility method in image_util to preform premultiplication.
...
Added visitor pattern to several different methods as well to prepare for image_data_any including compositing.

Updates for Ref #2594 and #2592 (Related to #2491 )
...
* Added support for scanline, stripped and tiled
* Added new configuration options for TIFF:
- method
- tile_height (Default 0)
- tile_width (Default 0)
- rows_per_strip (Default 0)
* Removed 'scanline' configuration option for TIFF.
* Changed RGBA TIFFs to be ASSOCALPHA rather then UNASSOCALPHA

image_data_8 -> image_data_gray8

image_data_float32 -> image_data_gray32f
NOTE: currently image_data_gray16::pixel_type = std::int16_t (signed 16 bit int) to match GDAL
should we support unsigned types?
