3d wire frame animated spaceship 1.0.0

3d animated Cobra MK3 ship from Elite!  Uses 16 bits integer math. This is an almost 1-to-1 conversion of the same program I wrote for the C64, but it runs a lot faster on the CommanderX16

Here is the (prog8) source code https://github.com/irmen/prog8/blob/master/examples/cx16/cobramk3-gfx.p8

I haven't figured out how to wait for the Vertical blank yet, to reduce the flickering perhaps...

Also I'm attempting to implement hidden line removal in the next version.
