Problem description

2D convolution export gives wrong results with in_channels>1

Reproducible example code

From test_export.py , the first test with on in_channel passes, the second with 2 in_channels fails.

    def test_Conv(self):
        model = aidge_core.sequential([
            aidge_core.Conv2D(1, 1, [3, 3], name="InputNode")
        ])
        initFiller(model)
        self.unit_test_export(model, "Conv", [[1, 1, 9, 9]]) # IS OK

or

def test_Conv_in_channels2(self):
        model = aidge_core.sequential([
            aidge_core.Conv2D(2, 2, [3, 3], name="InputNode")
        ])
        initFiller(model)
        self.unit_test_export(model, "Conv", [[1, 2, 9, 9]]) # ERROR !
