complex impedance crashes on dict_to_am because cryocard fw is tuple

The above line in new_ci_dset raises a ValueError because the cryocard_fw_version is returned as a tuple, which dict_to_am cannot handle. Either need to change this line to

ds.wrap('meta', sdl.dict_to_am(sdl.get_metadata(S, cfg), skip_bad_types=True))

or convert the cryocard_fw_version to a numpy array at some point within dict_to_am or get_metadata
