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

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.

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?

Updated tiff processing so now the encoder will utilize different types of data as well as will use Tile based encoding in most situations, if the image is large will revert to scanline based encoding.
