Adding seed for VB

[Skoricius]

PeriodicMirrorCircuitDesign in vb.py currently does not support seeding for reproducible results. But create_random_germpower_mirror_circuits method that it uses supports it.

To fix this, it would just be down to adding the seed to the __init__ method and passing it to create_random_germpower_mirror_circuits (line 259 in vb.py):

            circtemp, outtemp, junk = _rc.create_random_germpower_mirror_circuits(
                pspec, abs_clifford_compilations, depths, qubit_labels=qubit_labels, localclifford=localclifford,
                paulirandomize=paulirandomize, interacting_qs_density=samplerargs[0],
                fixed_versus_depth=fixed_versus_depth,
                seed=seed)

Thanks for reporting this. This was also noted as a subissue in #252. Hopefully should get to this soon.
