Restructure examples

# Feature
## Desired Behavior / Functionality
Based on how we present the example portfolio, it makes alot of sense to collect each use-case for all attacks under a single example folder.
This would also remove duplicate code related to data creation.

For example:
LOS:
- Setup
- MIA
- Synthetic attack
- GIA

Moreover, the examples should be cleaned up, e.g., report handler should not have its own. example.

## What Needs to Be Done
Take the use cases from the attack folders and add them to the same example folder with a common dataset creation code.

## How Can It Be Tested
Examples should run the same as before.
