Scottie S2 encodes only the first half of the image

I think the WIDTH = 160 in color.py is in error for Scottie S2.

I responded to a SSTV station in VK7 who had sent something in this mode, and it had been received just fine via slowrx.

I tried sending a response back, and this is what got encoded (and decoded)

RXSSTV also mis-decoded it:

I'll have a look and see if we can't get a better encoding in the S2 mode.
