Changed the portrait to switch according to Phee's current class

I added the portrait when Phee is promoted to Mage Fighter or Princess.

I have always thought that I should use the Mage Phee portrait created by 9-316, but until now, the portrait replacement process in this romhack did not have the palette switching function. So I could not use an image with a different palette than the normal one. I recently added a process that allows palette switching, and now it can finally be used.

Also, for some reason no one had ever pointed this out to me, Phee is a princess and needs to be able to be promoted to Princess. I took the opportunity to add a promotion, and now players can change her class to Princess if she uses Master Proof while she is Mage Fighter.

For this portrait, I modified and used the image of Mage Phee from 9-316's FE45 face graphic collection. Thank you so much.
