Ensures that the program exactly matches the devices topology.
As a result, this compiler only accepts :class:`~.ops.S2gate`, :class:`~.ops.MZgate`,
:class:`~.ops.Rgate`, and :class:`~.ops.MeasureFock` operations.
This compiler must be used with an X series device specification.
**Example**
>>> eng = sf.RemoteEngine("X8")
>>> spec = eng.device_spec
>>> prog.compile(device=spec, compiler="Xstrict")
