Based on the ExaTN buffer size constraint, the number of qubit lines that can be left open is dertermined.
Wavefunction slices and partial expectation values for those slices are computed. If MPI is present, the computation tasks are distributed across MPI processes.

Final sum reduce to compute the exp-val.
Added unit tests.
