This PR does the following refactorizations (sorry for packing many things together):
In
src/algorithms/contractions/bondenv/als_solve.jl: the axis order of tensors involved in the ALS optimization (in particular, theStensors and the rank-3 reduced bond tensor) is changed to more closely follow the MPS convention.In
src/algorithms/contractions/bondenv/benv_ctm.jl: CTMRG bond environment can now be constructed for an iPEPO, getting ready for finite-T FU.In
src/algorithms/time_evolution/apply_mpo.jl: The conversion of an open boundary MPS to Vidal gauge is improved by removing the constraint of the number of legs of each tensor.
