Unrolls (tagged) cirq.CircuitOperations while preserving the moment structure.

Each moment containing a matching circuit operation is expanded into a list of moments with the unrolled operations, hence preserving the original moment structure.

circuit Input circuit to apply the transformations on. The input circuit is not mutated.
deep If true, the transformer primitive will be recursively applied to all circuits wrapped inside circuit operations.
tags_to_check If specified, only circuit operations tagged with one of the tags_to_check are unrolled.

Copy of input circuit with (Tagged) CircuitOperation's expanded in a moment preserving way.
