Indirect imports not supported

If you import something in multiple steps you get an error like "WARNING: Cannot resolve import of $BLAH in $BAR [autoapi.python_import_resolution]". More specifically I'm refering to a scenario like this:

mypack.mod1:
```
from pathlib import Path
```

mypack.mod2:
```
from .mod1 import Path
```

This is arguably a bad practice and some linters complain about it but it would be nice if it worked.
