micropy install dependency issue

I'm new to micropython, so this may well be the fault of inexperience but here goes:

I'm using your great tool under Windows and VS Code.

I'm trying to run some code that depends on urlli.parse and urllib.parse depends on a module called collections.

I have run 'micropy install micropython-urllib.parse' and 'micropy install micropython-collections'

However, once uploaded to my pycom fipy I keep getting the error
```
File "/flash/lib/parse.py", line 32, in
ImportError: no module named 'collections'
```

However:
```
>>> os.listdir('lib')
['micropython-collections', 'micropython-hashlib', 'base64.py', 'defaultdict.py', 'hmac.py', 'mqtt_async.py', 'parse.py', 'urllib.py', 'warnings.py']
```

Any idea where I'm going wrong?

Reproduce the issue with `micropy install micropython-urllib.parse` and `micropy install micropython-collections`, then inspect the uploaded `lib` directory on the Pycom FiPy. Determine why the installed dependency is not importable; done when the dependency imports successfully or the issue documents the precise failure and expected behavior.
