PyTorch implementation of MQ-CNN and MQ-RNN

• MXNet implementation (in my opinion this is a little too dispersive)

Milestones for this one:

• [ ] Implementing core modules (with option for different encoders, but more compact than the MXNet one)
• [ ] Implementing LightningModule to handle training: this should take care of the "forking" logic described in the paper
• [ ] Estimator wrapper

Any updates on this?
