Addresses this issue by stacking all the frames from each filter together and playing them sequentially in a single gif.
Updates header information with instrument and filter from each frame.
Also removes the earlier behavior of adding an "empty" gif frame for any missing fits files that it cannot find. This would leave brief pauses in the movie and be included in the total frames number at the top of the gif.
