Oscillate I23 goniometer plan timing out prematurely

When using `bps.repeat` to oscillate the goniometer indefinitely between maximum positive and negative rotation, a timeout occurs before a full oscillation can complete. Furthermore, the plan itself cannot be stopped unless the terminal that it's running in is killed - only individual oscillations can be cancelled.
