`iter_bliss_scan_data` does not close the file properly except when using a simple loop on the iterator

Originally posted in ewoksxrpd!177 (comment 343417)

The file is apparently not properly closed when using something else than a simple loop on the iterator:

✅ Works

lima_iterator = bliss.iter_bliss_scan_data(
    filename,
    scan,
    lima_names=[detector_name],
    subscan=subscan,
)
for limadata in lima_iterator:
    image = limadata[detector_name]

with h5py.File(filename, "r") as h5file:
    pass

---

❌ Fails

Using next

for i in range(nbpoints):
    limadata = next(lima_iterator)
    image = limadata[detector_name]

with h5py.File(filename, "r") as h5file:
    pass

Using zip with another iterator

for i, limadata in zip(range(nbpoints), lima_iterator):
    image = limadata[detector_name]

with h5py.File(filename, "r") as h5file:
    pass
