Regions

Please use the layer that matches your region, or you will get a permissions error.

It turns out that providing public lambda layers is too unpleasant and buggy, so I recommend building your own layer and using it instead of publicly-provided layers.

Maybe AWS will make managing public layers less painful some day.
