partition custom dependency function - make the dataiku library available

When creating a custom dependency function, having access to Dataiku's API can be highly beneficial. In my experience, there was a frequent requirement to parse input partitions. Unfortunately, this was not possible because the Dataiku library was not accessible in the current namespace. Attempting to import the Dataiku library resulted in the error message 'No module named dataiku' * as discussed in this thread.

* : btw which code environment is used in the python dependency function?
