Comparison for very long lines could be truncated

[olivroy]

old <- paste0(rep("b", length.out = 10000), collapse = "")
new <- paste0(rep("c", length.out = 10000), collapse = "")
waldo::compare(old, new)

I think the diff provided by waldo is not informative. At this point, it is only useful to know they are different.

Could this be handled?

It causes my computer to lag because testthat prints a lot of output on failed snapshot tests in gt.

See tests/testthat/_snaps/image.md. When this test fails, it is not useful to show the full diff before displaying the offer for snapshot_review(), snapshot_accept()

A change in waldo's print method would be welcome!

Somewhat related to #57, but not directly since here you have two very long strings that are completely different.
