setcurve not correctly wrapped

the fix is in this commit: https://github.com/OpenWaterAnalytics/epanet-python/commit/b552db1cf673419c508b9e45c3ecb23ef1ac5445

... to use the function, follow the test as an example:

def test_setcurve():
    def make_array(values):
        dbl_arr = en.doubleArray(len(values))
        for i in range(len(values)):
            dbl_arr[i] = values[i]
        return dbl_arr

    epanet_proj = en.createproject()
    en.open(ph=epanet_proj, inpFile=example_1_path, rptFile='report.rpt', outFile='output.out')
    ok = en.addcurve(ph=epanet_proj, id="my_curve")
    curve_index = en.getcurveindex(ph=epanet_proj, id="my_curve")
    xvalues = make_array([1,2,3,4,5])
    yvalues = make_array([1,2,3,4,5])
    en.setcurve(ph=epanet_proj, index=curve_index, xValues=xvalues, yValues=yvalues, nPoints=5)
    count = en.getcurvelen(ph=epanet_proj, index=curve_index)
    assert count == 5
