1. Eliminate any unncessary "temporary" files. If we have a buffer, use it without creating any files on disk unless strictly required.
2. Use a shared pointer for data so that FITSView instances are implicitly sharing the same pointer. This finally allowed for Summary View to load the same view as FITS Viewer without incurring any memory penalty.
3. Add metadata to the FITSImage object to pass information that were passed before using AUX members of the blob which was not safe.
4. Add support to load RAW camera files directly in the FITS Viewer along with loading JPEG/PNGs that were added by Robert earliar.
