Add 2D Autoencoder and GMM Integration on Siracusa Target

[Aldrago98]

The goal of this branch is to implement a 2D autoencoder model integrated with a Gaussian Mixture Model (GMM) on the Siracusa target with Neureka support.

The implementation was developed incrementally through the following steps:

1. initial support for a generic target;
2. porting to Siracusa without tiling;
3. introduction of tiled support on Siracusa;
4. final integration with Siracusa + Neureka.
