Move to JuliaGeometry

[ViralBShah]

Hello - I wonder if it would make sense to move this package to the JuliaGeometry org, to make it easier for basic maintenance.

Actually, I just realized that there is Triangulate.jl in JuliaGeometry which is maintained. It would be great to add a link to that in the README and archive this package.
