GroupSeminorm.toSeminormedGroup
{E : Type u_5} → [inst : Group E] → GroupSeminorm E → SeminormedGroup EConstruct a seminormed group from a seminorm, i.e., registering the pseudodistance and the
pseudometric space structure from the seminorm properties. Note that in most cases this instance
creates bad definitional equalities (e.g., it does not take into account a possibly existing
UniformSpace instance on E).
