sixel: allow slightly poorly formed sixel data

Browse Source 
The issue appears to be due to a rogue trailing semicolon in the input
data.  Support for this appears to be mixed: an online converter didn't
produce valid output, but image magick's convert utility accepted it.

This commit allows an optional trailing semicolon at the end of the
color definition regex and enables wezterm to render the image.
