Convert Sparse matrix to a pauli sum #8529
Description
Feature details
I want to convert a scipy sparse matrix into a sum of Pauli strings directly using qml.pauli_decompose without converting to a numpy array first, since for larger arrays (e.g. 16 qubits) the np version becomes too large>
see https://discuss.pennylane.ai/t/how-to-pauli-decompose-a-sparse-matrix/8436/8?u=ruvdrsti for code example.
