[IO-1464] add in unknown parsing for WFTypes

[Nathanjp91]

Problem

WFType enum doesn't accept unknown values and this breaks certain testing with older/experimental Workflow types

Solution

Introduce default parsing that accepts unknown values and casting them to an UNKNOWN enum type

Changelog

Workflow stage enum no longer breaks on experimental and testing types

IO-1464 BUG: Get workflows raises error on meta

During dogfooding, this code:

from darwin.future.meta.client import MetaClient
from darwin.future.meta.objects.dataset import Dataset

client = MetaClient.local()

team = client.team
team_slug = team.slug

datasets = team.datasets.where(name="contains:error-test")
workflow = client.workflows

print(list(workflow))

for dataset in datasets:
    dataset.workflow()

    print(dataset.item_ids(team_slug))

raised this error

The above exception was the direct cause of the following exception:

Yep, all good.
