Error during iteration is not recoverable

[digizeph]

For example, during iteration, network disconnection could happen. In that case, the parser correctly logs the error, but the downstream consumer is not able to programmably detect such errors, and therefore resulting in incomplete reading of MRT files.

A work-around is to download remote files first before processing with OneIO. Errors during download is detectable and recoverable.
