Possible typo in make_arbitrary_rf.py

[tblazey]

Line 72 of make_arbitrary_rf.py is:

signal = signal / bp.abs(np.sum(signal * system.rf_raster_time)) * flip_angle / (2 * np.pi)

I'm assuming 'bp' is supposed to be 'np'

Also, I think you need parentheses around 'rf, gz' in line 124. Right now it reads:

return rf, gz if return_gz else rf

which returns two copies of rf.

@tblazey I am not able to find this typo even as early as commit 5ca1035 (which was the latest commit at the time you opened this issue, 11 days ago). Did you pull the latest dev version? Also, the return statements between lines 144-147 should avoid any duplicate returns. If you are still facing that problem on the latest version, could you share code so I can reproduce the bug on my end?
