Description
Generalize expect to two wave functions, i.e. expect(phi, "Sz", psi; range=1:N). However, maybe this is no longer a good name for the operation, maybe inner(phi, "Sz", psi; range=1:N) might be a better name?
Also need to coordinate with the notation proposed in ITensor/ITensorMPS.jl#58.
Inspired by this support question.

Research direction
Start by inspecting the existing expect operation and the notation proposal in ITensor/ITensorMPS.jl#58. Determine whether the API should be generalized under expect or renamed to inner, and coordinate the two-wave-function notation before implementation. Done means the naming and notation are agreed and the requested operation is defined consistently.
