Changes as of Thursday

I'm tired.

* Communication with Kurt's CTL simulator is working!  Bugs and logic with 0x1104 packets have now been fixed
* New way of managing camera settings, and the PYAS and RAS can be configured independently (with a proliferation of new commands to do so, see Google Drive)
* Added ability to override the camera's image with one from a FITS file (disabled by default, of course)
* New logic to "walking" through limbs and fiducials
* Each requested image over the science-stream produces a onboard binary file of the packet stream.  This can be removed in the future, but is useful for debugging.
* The bitfields are now properly ordered for the science-stream specification (SAS-GSE needs to update its submodule).  Unfortunately, there's still some other undetermined bug that's preventing them from being able to reconstruct our images, though.

Merging immediately
