Improved version of theme inspired by Metroid Prime Remastered

Improvements and other changes include:
- Official artwork of Samus for the top screen (now scaled better)
- In-game screenshot of the game's intro for the bottom screen
- More fitting color choices for the menu buttons and custom folder texture
- Metroid Prime Prologue Theme replacing the Frigate Orpheon theme, to better match the image on the bottom screen

(If you wish to revert to the previous song, look for each version of the theme in the "Themes" folder of your SD card, assuming you have both downloaded, and look for a file named bgm.bcstm. Feel free to replace them as you wish)

Wanted to do this game justice by improving upon my previous upload, now that I have more experience making custom themes. Original version: https://themeplaza.art/item/85801
