Tasks outside qudi-core are not found

What is affected by the bug?

Similar to adding additional fit-methods, I expected that it would be possible to include tasks by placing the corresponding python files into 'src/qudi/tasks' of a different project (so not qudi-core). This, however, seems not to work. After moving these python files into the tasks-folder of the qudi-core-module, everything works as expected (so python syntax or similar should not be the problem).

When does the bug occur?

Whenever trying to add tasks from a different project.

How do we replicate the issue?

In a different project (for example the qudi-iqo-modules), create a folder under 'src/qudi/tasks' and put a corresponding file into it (for example simply copy present test_task file and change the task names).

Expected behavior

From my understanding, it should be possible to add tasks without putting them into the qudi-core-project directly.
