Describe your changes

Update minimum version of dataclass-wizard to 0.29.2 which fixed bug which meant it wasn't possible to define Union types while checking that all keys in the loaded yaml-config file matched a field in the config dataclass (rnag/dataclass-wizard#137). The pressense of this bug meant in neural-lam that we had to keep raise_on_unknown_json_key to its default False value. We should ensure that people have a version of dataclass-wizard installed that means we can check the config yaml against the config dataclass while supporting union types.

I have run the tests both against 0.29.2 and also 0.35.0 (which dataclass-wizard>=0.29.2 currently resolves to) of dataclass-wizard.
