handling color in output

Hi-
Using pytest-azurepipelines, and ran into an issue where [the ANSI escape codes are being shown as-is in the Tests tab](https://developercommunity.visualstudio.com/t/support-colors-in-Pipeline-Tests-view/10878319). Is the workaround to set `--color=no`/[`NO_COLOR`](https://docs.pytest.org/en/stable/reference/reference.html#envvar-NO_COLOR)? If so, might make sense to mention that in the README here, as I assume everyone would run into that.

Likely related: https://github.com/pytest-dev/pytest/issues/12365

Thanks!
