Describe the enhancement requested

Hello,

As part of the development efforts for Sparrow, we aim to utilize Archery to ensure our library functions correctly using the integration tests. Currently, Archery supports running several "official" implementations.

To enhance flexibility and usability, I am preparing a pull request that introduces an option allowing users to specify the path to their own library for integration tests. This feature will enable users to test their custom implementations seamlessly within the Archery framework.
