Example code does not error on opening v0 dataset model

[BrianMichell]

• Ingest SEG-Y to MDIO using stable v0 Python command.
• $ ./real_data_example --print_dataset --dataset_path="ingested_mdio"
• No output to terminal.

The expected output should be an error message regarding failure to parse schema.
Need to investigate whether this is an issue in the API skipping some step or the example code needing to be updated.

The behavior is from the example not printing the error status on failure. The returned error for opening v0 is very opaque and should be improved.

Error: NOT_FOUND: Error opening "zarr" driver: Metadata at test.mdio/data/.zarray does not exist

This error is due to the v0 data being further broken down into transpose chunked volumes.
