[cbjuan]

Summary

Fixes issues with ECR gates. Fixes #73 and continues #63

Details and comments

As commented in the issue, this issue comes from Qiskit

Changes verified using the following code:

from qiskit.circuit import QuantumCircuit
from qiskit_ibm_transpiler.transpiler_service import TranspilerService
from qiskit_ibm_runtime import QiskitRuntimeService

num_qubits = 16
circuit = QuantumCircuit(num_qubits)
for i in range(num_qubits - 1):
    circuit.ecr(i, i + 1)

runtime_service = QiskitRuntimeService(channel="ibm_quantum")
backend = runtime_service.backend("ibm_strasbourg")

cloud_transpiler_service = TranspilerService(
    backend_name="ibm_strasbourg",
    ai="false",
    optimization_level=3,
)
transpiled_circuit = cloud_transpiler_service.run(circuit)
print([data.name for data in transpiled_circuit.data])
