Need for better visualizations

[SaashaJoshi]

The pipeline requires cleaner visualizations for the different models available. For example, QuantumConvolutionalLayer and QuantumPoolingLayer2D must be visualized as individual multi-qubit gate structures in the circuit.

Should also look into better visualization techniques, if possible.

To convert a circuit to a gate, for example to represent QuantumConvolutionalLayer as a single gate, refer to the following in-built function by Qiskit: circuit_to_gate
