Added fake data generator + gen. data; [skip ci]

Added a script to generate fake data. Trained and saved a synthetic data
generator model using the SDV library. Updated requirements.txt to
include the new dependencies. This feature will be useful for simulating
the inference and monitoring parts of the workflow, which are planned
to be added soon.
