Chesapeake7 doesn't have an embedded color table

[calebrob6]

All the tiffs in the Chesapeake series have embedded color tables except for the Chesapeake7 tiff. This causes the cmap = src.colormap(1) line to throw a ValueError.

The colormaps for the other files are all the same:

{0: (0, 0, 0, 0), 1: (0, 197, 255, 255), 2: (0, 168, 132, 255), 3: (38, 115, 0, 255), 4: (76, 230, 0, 255), 5: (163, 255, 115, 255), 6: (255, 170, 0, 255), 7: (255, 0, 0, 255), 8: (156, 156, 156, 255), 9: (0, 0, 0, 255), 10: (115, 115, 0, 255), 11: (230, 230, 0, 255), 12: (255, 255, 115, 255), 13: (197, 0, 255, 255), 14: (0, 0, 0, 255), 15: (0, 0, 0, 255)}

however the class mapping for the 7-class version is different:

We can probably just embed the appropriate color maps directly into the class.
