Update "About" description on github

[ramarty]

@g4brielvs Could we update the "About" section on Github? I think this is done through "settings", but I don't have access to that on World Bank repos.

Right now it reads:
Create Georeferenced Rasters of Nighttime Lights from NASA Black Marble data

Which summarizes the bm_raster function, but not bm_extract. So maybe we change to something more general -- like:

Facilitate analysis of NASA Black Marble data

https://worldbank.github.io/blackmarbler/

If that makes sense, then let's make the text similar for blackmarblepy

@ramarty I just promoted the team permissions to "Admin". It should do the trick.

Right now it reads: Create Georeferenced Rasters of Nighttime Lights from NASA Black Marble data

What about: "Georeferenced Rasters and Statistics of Nighttime Lights from NASA Black Marble"?

@g4brielvs ohhh yes I like that better, let's do that!

@g4brielvs Thanks for updating! I think there's currently a tiny typo (it says Ceoreferenced ;)
