Compatibility with phpunit 9.x

[mvorisek]

This is a feature request. Please make this package compatible with phpunit 9.x so it can be used in projects that still need to support phpunit 9.x which is still very popular - https://packagist.org/packages/phpunit/phpunit/stats (about 70% market share).

Please convince @johnkary instead to merge johnkary/phpunit-speedtrap#98.

I am aware of that PR, but this package seems to be well tested and maintained, so adding backcompatibility should not be that hard and can help this package become popular 🚀
