Description
Introduce functions like setlpos!(p, l) for AbstractProjMPO types that in the simplest case does p.lpos = l (and same for rpos). This could help simplify the code logic for DiskProjMPO which needs to keep track of both the position and the position of the cache.

Research direction
Start by locating the AbstractProjMPO types and the DiskProjMPO implementation, then review the linked discussion in ITensors.jl pull request 648. Determine how setlpos! and the corresponding right-position function should update positions and cache-related state. Done means the new functions work for the simplest AbstractProjMPO case and simplify DiskProjMPO position tracking.
