pyGSTio/pyGSTi: Version 0.9.8.3

HOTFIX This patch includes a number of minor bug fixes: Fixed the issue of weird ('*',) line labels in circuit construction routines when used with multi-qubit notation circuits, e.g. (0,)-labeled circuits getting erroneous ('*',0)-labeled circuits created. Fixed bug in optools.fidelity for special case of trace-reducing rank-1 ops. Now handling sqrtm failure in optools._hack_sqrt as a warning instead of assertion error
