Description
The TaylorCluster algorithm's "loopback" algorithm involves removing the rows and columns that are labled by level-labels only containing 1's and "3"'s. Currently the rows and columns were removed using the right-virtualsize of the Hamiltonian as the "3" level.
To be correct for non-square Hamiltonians, we need to remove the columns with a "3" level based on the right-virtualsize and the rows based on the left-virtual size. This PR implements this.
