Update grandfibermap to describe all slit holes, and with complete connector mappings.

The current grandfibermap only describes the science fibers: all fibers which are terminated at a cobra. We need to have a map which describes all the slit holes, including the engineering and blank fibers.

Also, recent work has shown that some of the gang connector mappings might not not correct? These are necessary to map SuNSS fibers to the right slit holes, regardless of the chosen module, since we essentially replace one module's B-C segment with a B-to-S(unSS) segment.

grandfibermap is generated using JEG code. I imagine that code should be updated and rerun. If it is surgically exciseable we probably should do so and recode it in pfs_utils or somewhere like that. Some of us even like Forth!
