Circuit renderer does not handle Phase OpType

[CalMacCQ]

Adding a OpType.Phase to a Circuit seems to cause the circuit render to not show the circuit diagram.

We could make it so that the OpType.Phase is invisible and add the numerical value of the phase alongside the Circuit somewhere. We should also think about how to represent conditional phase as this is what the Phase OpType was introduced to handle.

circ = Circuit(2).H(0).CX(0,1)

render_circuit_jupyter(circ) # This works fine

But If I then add a Phase OpType...

circ.Phase(0.25)
render_circuit_jupyter(circ) # diagram doesn't show
