[IO-1230] Fix and test for complex polygons

[Nathanjp91]

Problem

Latest fix for semantic mask didn't account for the problem of having complex polygons vs simple polygons

Solution

Polygon offsets now account for complex polygons and deal with simple/complex accordingly

Changelog

Fixed a problem with new semantic mask export logic not accounting for complex polygon datasets with out of bounds polygons. It should now handle complex polygons.

[linear]

  V2
  Environment (production/staging; browser and OS version)

Impact
All (all Darwin users are impacted)
Priority
🟠 High - important issue, but has workaround
Steps to reproduce
Run the below Python script for any remote dataset with items in a workflow and observe the above described problem

from darwin.dataset.remote_dataset_v2 import RemoteDatasetV2
from darwin.client import Client

client = Client.from_api_key('ApiKey')
dataset = RemoteDatasetV2(client=client, team='team_slug', dataset_id=dataset_id, name='dataset_name', slug='dataset_slug')
items = [i for i in dataset.fetch_remote_files()]
print(items)
Expected Behaviour
