Function alterF

alterF<F>(
f: TypeClass.Functor.Functor<F>,
): <V>(
updater: (oldEntry: Option.Option<V>) => Get1<F, Option.Option<V>>,
) => <K>(key: K) => (m: Map<K, V>) => Get1<F, Map<K, V>>
Alternates entry with the key over the functor F. This lets you insert, modify and remove an entry contained by F.
