`EA` covers both Ceuta and Melilla; the Ceuta-specific code is `ES-CE`.
This is also consistent with other flags for subdivisions of Spain,
in particular Melilla, which already uses `ES-MA`.
The bottom blue stripe should take 1/4 of the height of the flag.
The middle white and red stripes, as well as the stars, were scaled up
to implement these proportions.
As a side effect of this change, the flag now works better at small sizes.
The flag of Cape Verde had the stripes and stars positioned too low.
The top blue part is supposed to occupy half of the height of the flag.
I've edited the geometry so that the white and red stripes start at 50%
of height of the circle. I moved the stars upwards accordingly.
