Added new font based on GNC255 pilots guide illustrations for the large frequency display.
Tweaked the layout to fit.
This is very close to the original, it has just 1 pixel of space on left and right sides, so it fills the space better. The orignal GNC255 display is lower resolution and also has larger pixels, so the extra two pixels of space between numbers makes it look better.
