Description
Thank you for developing the nice library!
I am wondering how to generalize the fitting algorithm to MPO-MPO multiplication. I am slowly understanding the internal structure of this library. This could be achieved by generalizing ProjMPOApply.
https://github.com/ITensor/ITensorTDVP.jl/blob/main/src/projmpo_apply.jl
But, the function tdvp is specialized to MPS. I am not sure if this restriction is strict. Is generalizing it to MPO possible technically?

Research direction
Start with src/projmpo_apply.jl, especially ProjMPOApply, and inspect how tdvp is specialized to MPS. Determine whether the fitting algorithm can support MPO-MPO multiplication; done means the relevant generalization is technically supported and covered by appropriate tests.
