test: add portrait fixture images and extreme-height regression test

Add test-portrait-tall.png (200x4000) and test-portrait-extreme.png
(100x6000) fixtures. Update crop overflow tests to use fixture files
instead of generating images at runtime, and add a second test case
for extremely tall images.
