this dumb pipeline enabling color HDMI on a Pico is turning out to be super interesting. RGB332 is fun, and I worked out a 62-color palette that fits into 6 bytes, so a normal full row of 640 color pixels fits into 480 bytes, which is nice and tidy. the device only has like 512KiB of RAM so this is a really tight and fun constraint to program against.

also since it's 62 that gives us two extra indices so I allocated one to pseudo-transparent.
