Starting a new extractor project - "Extractor" has incompatible type

Hey ​@Michael Tievenow Thanks for bringing this up. I will create a task to track this bug and work on it.

The issue that you are seeing is because of the Mypy saying that it is expecting the method run_extractor to have the following set of arguments in this order:

• CogniteClient
• AbstractStateStore
• Any
• CancellationToken

or 

• None as in no arguments at all

Currently the arguments of the method run_extractor are of the following type:

• CogniteClient
• AbstractStateStore
• Config
• Event

The problem is being caused by the type of the last argument which is of type `Event` but is expected to be CancellationToken

While we look into fixing this issue with `cogex init`, I wanted to provide the solution so you are unblocked by this:

In the file `csv_extractor/extractor,py`,

• Add the following import statement:

from cognite.extractorutils.threading import CancellationToken

• modify the definition of the method `run_extractor`

def run_extractor(cognite: CogniteClient, states: AbstractStateStore, config: Config, stop_event: CancellationToken) -> None:

This should fix the problem of you being unable to push the code.
