The wrappers provide a simple way to measure not only global functions
but also methods of psi and the simulation class.

Here, the fix of 2a5052a
is not yet included, so the next commit is a cherry-pick merging only that.

This is necessary to avoid special-cases inside measurment functions for
grouped sites, orthogonalExcitations and others. The model is guaranteed
to be compatible with the state.

This is a cherry-pick of a previous commit 2a5052a
not yet merged in the main branch, but already existing other branches, in particular excitations_science and vumps.

E.g. tenpy.simulations.measurement.bond_dimension(...) is now tenpy.simulations.measurement.m_bond_dimension(...)
