* Load tracing filter only from config and simplify logic.
* Configure the state storage in the config, not an environment variable.
This also changes the config so that the path is always set rather than being
optional, because Zebra always needs a place to store its config.
* Add support for errors in zebra_test::Transcript
* test transcript with an error checker
* switch to option instead of MockError
* update docs
* dont use verifier against ready_and
* cleanup exports and add docs
* handle todos
* fix doctest
* temp: use cleaner error handling example
* add ability to test only for presence of error
