message_ix_models.tests.model.test_snapshot.unpacked_snapshot_data(test_context, request)

Already-unpacked data for a snapshot.

This copies the .csv.gz files from message_ix_models/tests/data/… to the directory where they would be unpacked by .model.snapshot._unpack. This causes the code to skip unpacking them, which can be very slow.
