Add signatures to the Western African States [resuelto]

I have made a spreadsheet with all the signatures from the Western African States.

Folder with all the stuff:

Spreadsheet:

Yellow Wikidata codes means I'm in doubt of if it's the right one.

Mistakes may have occoured. Sources in the bottom of the spreadsheet.

Thanks :D
