Determine if mount guiding corrections are non-blocking

[wtgee]

When we correct the tracking we do a move_ms command in a specified direction (east or west for RA and north or south for Dec) but we issue the Dec command first and then immediately move to the RA then start the waiting timer.

During observations on PAN001 it seemed like an error in Dec wasn't getting corrected so it steadily drifted further off. Changing the timer to wait for the Dec before issuing RA commands seemed to help.

Need to determine (in the lab) if you can move both axis simultaneously.
