Add a pixel test with invalid bfranges inside ToUnicode map.
The test file in crbug.com/1021762 is currently rendered correctly
because https://pdfium-review.googlesource.com/62550 added more
validations when parsing ToUnicode map with invalid bfranges.
However, ToUnicode map shouldn't have affected the rendering result for
this issue and more future fixes are needed to completely fix it.
This CL adds a simple test that represents the issue to make sure
future fixes won't affect the rendering result.
