ATS-770: Tech Debt: Transforms - Tiff (via ImageMagick) - add unit tests for supported transforms (#254)

* ATS-770: Tech Debt: Transforms - Tiff (via ImageMagick) - add unit tests for supported transforms

- add unit test for image/tiff -> image/*
- increases ImageMagickTransformationIT by x32 test transforms (to x440)
- add transform option for single page for specific case of source "tiff" (to specific targets)
