Get IMGSTAT into the maude decom aca packets / images

[jeanconn]

Need at least IMGSTAT. Nicer to have them in English.

Question... what do you prefer?

1. one column called IMGSTAT
2. one column for each flag
3. both

(as far as I understand, we want at least No. 2)

Any preference on names? Well, I guess you will tell me this during the PR.

IMGSTAT columns:

• IMGSTAT (unsigned)
• SAT_PIXEL (bool)
• DEF_PIXEL (bool)
• QUAD_BOUND (bool)
• COMMON_COL (bool)
• MULTI_STAR (bool)
• ION_RAD (bool)

I just pushed a change for this and forgot to mention it in the git log: a42f931f5...

Note that, as we discussed, IMGNUM, FID, IMGFUNC appear twice in this code (in header 1 and header 2). This code ignores the values in header 2.

Also, there is a flag for invalid checksum in command groups. It seems to appear twice, in the 3rd and 4th word of the ACA packet. I didn't ignore any because I am not sure.
