unscii: cleanup and split outputs

The font is very large and duplicated across many formats, some of
which cannot be compressed, like `.hex` or `.svg`.
For normal use (eg. X11, GTK applications) these formats are not
necessary, so they are moved to another output reducing the default
closure size.
