Package: @effect/typeclass
Module: Monoid
This function creates and returns a new Monoid for a struct of values based on the given Monoids for each property in the struct.
The returned Monoid combines two structs of the same type by applying the corresponding Monoid passed as arguments to each property in the struct.
The empty value of the returned Monoid is a struct where each property is the empty value of the corresponding Monoid in the input monoids object.
It is useful when you need to combine two structs of the same type and you have a specific way of combining each property of the struct.
