Add in Africa/ Modest, Asia, Latin America, and Oceania character sets

[marlitas]

This sim needs the initial structure to change character sets based on the region and culture preference.

The original artwork is fairly high-res. It's also mipmaps. Can we discuss the ideal size to export this artwork at?

Character sets are uploaded!

The missing levels for Africa-Conservative should come from Africa, and the missing levels for Oceania should come from Asia.

All the character sets are loaded in now. @amanda-phet could you review to ensure it's all looking good? Thanks!

1. There are a few PNGs I would like to update and will upload those today.

2. The layout of the screen looks really odd- the text is lower and the buttons are smaller. I am mainly concerned about the interference of the text and buttons.

Current:

3. I'm also wondering if this sim should have a "multicultural" random option, since the USA version is all the same person. Can we randomly select from a different region for each screen?

Yeah that layout is an outstanding issue involving the LevelSelectionButtons. JO, CM, and I are meeting today and may have a solution, but I have a feeling the final solution will be during the LevelSelection design meeting next week.

The SVGs are looking good to me and "multicultural" is working as expected.

Closing since the artwork is looking good. The layout issue with the texts being close to the buttons is being tracked here phetsims/vegas#120.
