Save multiple guide calibration data
The idea is to be able to run guiding without having to run calibration every time. One limitation is that DEC swap depends on mount. Right now, calibration would let us know if DEC swap is required or not post a meridian flip.
If we save multiple calibration information that includes camera, mount, and side of pier, then as soon as we have calibration data from BOTH sides of the pier, we can know the DEC swap behavior for this particular setup and perhaps we can re-use the calibration info without any side effects.
