Access preflight and acquisition

CLI

# Read-only preflight
eyehub download chaksu --data-dir ./data --dry-run --json

# Explicit transfer, only when preflight reports supported behavior
eyehub download chaksu --data-dir ./data

Python

from eyedatahub.acquisition import preflight_dataset
from eyedatahub.datasets.registry import REGISTRY

ds = REGISTRY.get_dataset('chaksu')
print(preflight_dataset(ds, './data'))  # no transfer
