cli: fetch extended evet types from contract config

The user should specify it via parameter's `extendedtype` field and
via upper-level `namedtypes` field of the contract configuration YAML.

Also, as we have proper event structure source, make the `--guess-eventtype`
compilation option and make event types guess optional.
