Separate model-specific and data-specific hyperparameters

Is your feature request related to a problem? Please describe.
Right now, PrivacyRaven mixes all of the hyperparameters necessary to train a substitute model into a single dictionary. This should be replaced with Lightning Data Modules and/or other structures to clarify the role of each parameter and make it easier to extend PrivacyRaven for different tasks. This may require automatically turning all synthesized data into a Data Module.

Detail any additional context.
