Add `qc2Data` Pennylane plugin

[Cmurilochem]

Following our list of task priorities, we also need to develop a Pennylane plugin in order to connect it directly with qc2Data and QCSchema and FCIDump data schema without having to rely on Qiskit-Nature first.

Alternatively, we could still rely on Qiskit-Nature but instead use much of the capabilities of the new release of PennyLane. There are currently implemented native functions from_qiskit and from_qiskit_op that directly convert Qiskit QuantumCircuit circuit and SparsePauliOps to Pennylane format.
