Cutqc cut method fails with the latest release of qiskit

[hrushikesh890]

With the latest release of qiskit, some elements of DAGNode have been deprecated.
In cutter.py
if u.type == "op" and v.type == "op":
throws the following error
File "cutqc/cutter.py", line 341, in read_circ if u.type == "op" and v.type == "op": AttributeError: 'DAGInNode' object has no attribute 'type'

Solution is simple
Replace faulting line with
if (type(u) == DAGOpNode) and (type(v) == DAGOpNode):
