DRAFT: Fix retry

[payno]

Looks like that on recent version of h5py we can get the following error from using retry (that used to be handled on the older version - < 3.10):

period = 0.01, spectrum_cu_from_larch = <est.core.types.spectrum.Spectrum object at 0x7fa83e658b10>, tmpdir = local('/tmp/pytest-of-payno/pytest-60/test_get_data_0_01_0')

    @pytest.mark.parametrize("period", [0.01, 0.1, 0.5])
    def test_get_data(period, spectrum_cu_from_larch, tmpdir):
        filename = str(tmpdir / "data.h5")
        scan = "1.1"
        npoints = len(spectrum_cu_from_larch.energy)
        positioners = {"energy": spectrum_cu_from_larch.energy}
        detectors = {"mu": spectrum_cu_from_larch.mu}
        npoints = spectrum_cu_from_larch.energy.size
        blocksize = max(int(npoints / 10), 1)
        est_time = npoints / blocksize * period
        tmax = time.time() + est_time + 5
        print("Estimated scan time", est_time, "s")
    
        urls = [
            f"silx://{filename}::/{scan}/measurement/energy",
            f"silx://{filename}::/{scan}/measurement/mu",
        ]
        with nxwriter_process(filename, scan, positioners, detectors, blocksize, period):
            nprogress = 0
            while nprogress != npoints:
>               data = [get_data(url, retry_timeout=3) for url in urls]

For info on my use case the namespace is always None. Which seems unexpected

    for frame in traceback.walk_tb(e.__traceback__):
        for namespace in (frame[0].f_locals, frame[0].f_globals):
            if namespace.get("__package__", None) == "h5py":
                return True

indeed the troubles is already fixed by 16888f0
