Construct a SimpleLayerGenerator.
Args:
two_qudit_gate (Gate): A two-qudit gate that starts this
layer generator's building block. (Default: CNOTGate())
single_qudit_gate_1 (Gate): A single-qudit gate that follows
`two_qudit_gate` in the building block. (Default: U3Gate())
single_qudit_gate_2 (Gate | None): An alternate single-qudit
gate to be used as the second single-qudit gate in the
building block. If left as None, defaults to
`single_qudit_gate_1`. (Default: None)
initial_layer_gate (Gate | None): An alternate single-qudit
gate that creates the initial layer. If left as None,
defaults to `single_qudit_gate_1`. (Default: None)
Raises:
ValueError: If `two_qudit_gate`'s size is not 2, or if any
of the single-qudit gates' size is not 1.
ValueError: If `single_qudit_gate_1`'s radix does not match
the radix of `two_qudit_gate`'s first qudit, or if

of `two_qudit_gate`'s second qudit.
