FEAT: Better error handling in robinhood

Rationale

For now, in case of an error in the C-part of robinhood engine, we don't know the real reason for the failure and we only can return status::UNKNOWN_ERROR.

Description

We should extend returned values from the C functions to return more appropriate statuses than just unknown error.
