linsyking/elm-regl/9.1.0

NOTE: the latest version is 10.0.0

Renamed to elm-messenger/elm-regl. That is where the repository lives now. It has not been published as a package under the new name.

Versions published as linsyking/elm-regl still install under that name. 5 versions of 15 come from the new location (see their notes).
