Unable to set multiple laser drives for qubits

[ajgpitch]

It does not seem possible to add drives of say sigma_z and sigma_x for a qubit via the interface. The radio buttons for setting the laser interaction operator should be checkboxes (functionally, not visually). I am fairly sure that this did once exist, hence reporting as bug rather than enhancement, although I may be confused with having multiple coupling interactions.

When loading the Larmor precession demo, initially in the details section this is shown (incorrectly) as just a sigma_x drive, but if one toggles the laser off and on, then the sigma_z and sigma_x terms are shown in details, though not displayed as such in the lab interface.
