Add a new member 'sextants' to the terminfo cache (both notcurses and ncvisual contain one of these, and both initialize it the same way -- interrogate_terminfo()). Add a new function, 'notcurses_media_defblitter()', and deprecate 'ncvisual_default_blitter()' (the latter didn't receive enough information to return NCBLIT_3x2). Update all callers. Add new *internal* function rgba_default_blitter(), so this logic can be freely changed in the future. If sextants are available, and we're scaling, return NCBLIT_3x2. Once we detect sextant availability, we'll have sexblitter as a default -- stay tuned! #1114
