gui tabs: use different goal image for mirror alignment depending on sensor

each sensor (size) needs a different goal image
driver: add new drivers to the list of drivers
driver lle: check harder that a device is NOT a LLE

it's not that hard to return something different from 0 or ffff, so check multiple times
driver tlfw: detect device even if it has first received garbage

Other drivers looking for their devices (ex: LLE) would cause the filter wheel to return error when
receiving *idn?. So first clean up the command buffer of the device.
