Unrolls (tagged) cirq.CircuitOperations by inserting operations using EARLIEST strategy.

Each matching cirq.CircuitOperation is replaced by inserting underlying operations using the cirq.InsertStrategy.EARLIEST strategy. The greedy approach attempts to minimize circuit depth of the resulting circuit.

circuit Input circuit to apply the transformations on. The input circuit is not mutated.
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 using EARLIEST strategy.
