Remove global config for dataclass_wizard

[leifdenby]

In working on the yaml configuration files in neural-lam I realised that setting global configuration for dataclass_wizard is a very bad idea. This should be obvious because different uses of dataclass_wizard might have different needs for configuration, however previously I didn't realise how to set the config when using dataclass_wizard.YAMLWizard. It turns out the key is to 1) also inherit from dataclass_wizard.JSONWizard (and make this the primary parent class) and 2) use dataclass_wizard.JSONWizard.Meta to define the config (not dataclass_wizard.YAMLWizard.Meta since this class does not exist).

This commit removes the global config for dataclass_wizard and only sets the configuration on mllam-data-preps mllam_data_prep.config.Config config dataclass.

Hopefully the description above is clear @observingClouds, if not let's have a chat tomorrow. I would like for this to get into the next release, so I will bring it to the developer meeting next week.

So if I understand correctly, the code here is about ensuring that all unkown parameters in the config files will raise an exception. Recently the GlobalJSONMeta class has been used with the major downside that also other modules loaded at runtime will be affected by this global setting if they use dataclass_wizard.

With this PR you ensure that only the local dataclasses are affected as it now becomes part of the Config dataclass and is no longer global.

Not being familiar with the dataclass_wizard the suggested change is clearer now.

That's exactly right, yes! Thanks again for reviewing this.

Thanks! Although I hadn't written anything in the changelog yet 😄 But I will do that when I prepare the v0.5.0 release

Right, sorry about that 😅 Yes, please fix it with the 0.5.0 release. Maybe a good reason to have the PR template also here for MDP?
