riders: groups of spots onscreen

[rp-jt]

In Sunset Riders, during some parts of the game, an object conformed by a group of colored dots can be spotted

I filtered this scene to leave the dots as the only object, they seem to be drawn for scan_obj==0 (at least in this scene)

It might be related to #742 and/or the protection chip

I think it is related to the protection chip indeed. MAME may have some comments about it but I think there are also ghost sprites on the MAME version.
