0d2eb9cb5f 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

bf5c532269 Series of changes for the tiff encoder: 
* Added configuration options for the TIFF encoder. The options are:
   - compression: adobe_deflate(default), deflate, lzw, none
   - zlevel: 0-9
   - scanline: 1,0 (Forces scanline encoding)
 * Fixed bug in encoder with scanline where memory was being modified
 * by TIFFWriteScanline. A buffer is now created for each row to prevent
 * modification of the underlying image_data.

38da080f82 make concrete image_data type names more expressive and explicit about color channels/depth: 
image_data_32 -> image_data_rgba8
image_data_8  -> image_data_gray8
image_data_16 -> image_data_gray16
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?
