Handle ignored message as a failure

[madchicken]

Description

This pull request includes a change to the error handling in the RowStream implementation in lib/src/stream.rs. The change ensures that the state is set to Complete(None) and an Error::RequestIgnoredError is returned when the summary is Ignored. This because the documentation states:

The IGNORED message indicates that the corresponding request has not been carried out.

For the RUN command the doc also says:

If the server is in a FAILED or INTERRUPTED state, the request will be IGNORED.

Error handling improvement:

• lib/src/stream.rs: Modified the handling of Summary::Ignored to set the state to Complete(None) and return an Error::RequestIgnoredError.
