ValueError in make_block_pulse.py when not difining the use parameter

Since https://github.com/imr-framework/pypulseq/commit/7542b39630c1c4cefc6eb5ded3ddb290a54e487c the _make_blockpulse.py throws the ValueError ValueError: Invalid use parameter. Must be one of 'excitation', 'refocusing' or 'inversion'. Passed: when use is not defined. The reason is that the default for use is an empty string now, but in line 64 you check for a None.

if use != '' and use not in valid_use_pulses:

Unfortunately you forgot to add a return in the else statement. It must be

    if return_gz:
        return rf, gz
    else:
        return rf

instead of

    if return_gz:
        return rf, gz
    else:
        rf
