extra half brite mode

Extra half brite mode allows us to use 32 colors as well as 32 "half brite" versions of those colors.

I added basic supprt to imagecon to output EHB mode data. It doesn't really do a great job of taking advantage of the EHB mode.

The only changes I made to the asm code to allow EHB mode was to add the 6th bitplane and make sure the copper reset the extra bitplane pointer.

We can see from the output that it's not earth shatteringly different.

64 color extra half brite

6 bitplanes

32 colors
