:meth:`.SparsePauliOp.from_operator` now uses an implementation of the
"tensorized Pauli decomposition algorithm" presented in
`Hatznko, Binkowski and Gupta (2023) <https://arxiv.org/abs/2310.13421>`__. The method is now
several orders of magnitude faster; for example, it is possible to decompose a random
10-qubit operator in around 250ms on a consumer Macbook Pro (Intel i7, 2020).
