feat: active project export data

[frederik-encord]

An example of how to use the Active dataset.
Note that you can choose to include data URIs.

from pathlib import Path


from encord_active.public.active_project import ActiveProject
db_path = Path("fruits_only/encord-active.sqlite")

project = ActiveProject.from_db_file(db_path, project_name="Fruits [Workflow]")

print(project.ontology)
image_metrics = project.get_images_metrics(include_data_uris=True, include_data_tags=True)
print(image_metrics.describe())

preds = project.get_prediction_metrics(include_data_uris=True, include_data_tags=True)
print(preds.describe())
