sdl2.ext.draw.fill: area should be able to be SDL_Rect

[knghtbrd]

If I set area to be a tuple, I get the correct fill. If I set it to SDL_Rect with the same contents, what I get is the entire surface filled.

Using 0.9.4 on Linux Mint 20 (Ubuntu Focal base). I'll fix my code—I intended this to be temporary code anyway.

Hey, sorry, for some reason I haven't been getting notifications for new issues! I'll make some time to tackle your issues and your PR soon, though that might not be until late this month as I have other projects that need work. Thanks for helping make this package better!

This seems like an easy fix, I'll add this after the 2.0.14 updates are done!
