csi: fix sub-parameter versions of 38/48 SGR escapes

Browse source 
Well this is embarrassing; the sub-parameter versions of the 38/48 SGR
escapes all required an extra ‘:2’ that wasn’t supposed to be there,
causing all the other sub-parameters to be shifted one step to the
right.

That is, foot expected e.g. 38:2:2:r:g:b, or 38:2:5:idx when the
correct sequences are 38:2:cs:r:g:b and 38:5:idx.

I.e. I mixed up the color-space ID (cs) of 38:2 with *type* of color:
RGB or indexed.

In addition to fixing this, this patch also adds support for a
“bastard” version of the sub-parameter based RGB escapes, where the
color-space identifier has been left out: e.g. 38:2:r:g:b. This
sequence is invalid, but applications tend to “forget” the color-space
ID...
