color: Implement Scottie DX, Wraase SC-2 120 and Wraase SC-2 180. (#37) 
* color: Implement Wraase SC-2 120 and 180.

* color: Implement Scottie DX

* color: Re-factor Wraase modes

`ColorSSTV` parent class actually implements the scan-line encoding we
need, however the challenge is that it seems the sync pulse requirements
differ for SC2-120 and SC2-180 just slightly.

I haven't figured out why, partially because there seems to be little in
the way of clear (and correct!) docs as to how SC2-120 is supposed to work.

* color: Fix Scottie DX timing

Using actual reference timing values from N7CXI Dayton paper.

Thanks to @Chris_J_Baird on Twitter reporting the issue:

> ColorSSTV.encode_line assuming its gets a tuple from __getpixel__
> had to make the Image.open() do a convert('RGB')
