Multi-image Tiff Writer

This writer will first write images on the fly and when finished append the file with an image file directory (IDF) for each written image. These IDFs present the tiff-reader with pointers to the actual image data.

Tiff files only support filesizes to a maximum of 4GB (2^32 bytes). Thanks to the work of [O.Hernandez](https://www.mathworks.com/matlabcentral/profile/authors/2917135-oscar-hernandez) there is also a Fast-BigTiff-Writer. Please use this version when tiff-files must be bigger than 4 GB.
