run individual tests where code has changed

pytest-picked looks great, but I often have 10s or even hundreds of tests in a single file.

It would be great therefore if this library could pick specific test rather than whole files.

I imagine this would be possible by introspecting git diff or similar.

I think this would be a great feature too! PRs are always welcome! :)

+1 this would simile awesome feature. Simile reason for use case, sometimes test file is large or tests can some time to run, so getting it down to run just the tests affected by diff would be great
