entrypoint: handle the sub-packages separately

Run the tests for each sub-package as a separate invocation.
Make the package selectable.
This has a few small advantages:
* When iterating on a single package the other packages do not run
* Better coverage summary line printed after each test
* Slightly better output with verbose test output
