Produces a SeminormedAddCommGroup E instance from a SeminormedSpace.Core. Note that if this is used to define an instance on a type, it also provides a new distance measure from the norm. it must therefore not be used on a type with a preexisting distance measure or topology. See note [reducible non-instances].
