Factor out ol.geom.Geometry.getLayoutForStride_
Factor out ol.geom.Geometry.getStrideForLayout_
Add ol.geom.flat.deflateCoordinate
Ensure endss is truncated if needed in ol.geom.flat.deflateCoordinatesss
Allow geometries to have null coordinates and add setFlatCoordinates
Rename ol.geom.Layout to ol.geom.GeometryLayout
Rename ol.geom.Type to ol.geom.GeometryType
