Revert "Remove code that tries to handle ANSI escape inputs"

This reverts commit 8174e02279. Turns out
it is needed for a common use case, see
https://github.com/sharkdp/bat/issues/2307.

It is not a clean revert, because I adjust CHANGELOG.md and also add a
comment to the test. I also had to resolve a small `use` conflict.
