🐞 Factories should be using ElectionGuard Sample Data

### Current Behavior

Both factories and subsequently the sample data generation should be relying on the **sample_data.zip** from the root `electionguard` repository.

### Expected Behavior

The `data` folder could be empty until after the data is pulled using `make environment`.

This is the data folder to be deleted:
https://github.com/microsoft/electionguard-python/tree/main/data

This involves updating `ElectionFactory`, `BallotFactory` and some of `SampleGenerator`
