Bug report: recursive_qs_search

[renezander90]

A error occurs when recursive_qs_search is applied to a network.Graph.

from qrisp import *
import networkx as nx

def test(G, qv):
    h(qv)
    
qv = QuantumVariable(1)
G = nx.Graph()
G.add_edges_from([(0, 1), (0, 2)])

with conjugate(test)(G, qv):
    h(qv)

Here, the conjugation environment applies recursive_qs_search to the arguments G, qv.
If G is a networkx.Graph this yields an error.

A workaround would be hiding the graph G:

from qrisp import *
import networkx as nx

def test_workaround(G, qv):
    def test(qv):
        h(qv)
    return test     
    
qv = QuantumVariable(1)
G = nx.Graph()
G.add_edges_from([(0, 1), (0, 2)])

test = test_workaround(G, qv)

with conjugate(test)(qv):
    h(qv)
