Duplicate qubit in gate append for fastOptimized qlassf

[dakk]

from qlasskit import Qint8, Qint16, Qlist, boolopt, qlassfa

@qlassfa(bool_optimizer=boolopt.fastOptimizer)
def test(a_list: Qlist[Qint8, 8]) -> Qint16:
    h_val = Qint16(0)
    for c in a_list:
        h_val = h_val + c
    return h_val

Raises:

Exception: duplicate qubit in gate append: [64, 64, 75, 83]

This also occurs using circuit_boolean_optimizer:

from qlasskit import qlassf, Qint4
from qlasskit.decompiler import Decompiler, circuit_boolean_optimizer

@qlassf
def qf(a: Qint4) -> Qint4:
    return a * a 

circuit_boolean_optimizer(qf.circuit())

Exception: duplicate qubit in gate append: [16, 16]
