IArray instances (Scala 3)

[TheDrawingCoder-Gamer]

Hello, I think that IArray should have the same instances that Vector does as they are basically (?) the same concept.

I would be willing to work on this.

Vector currently has: Traverse, Monad, Alternative, CoflatMap, Align, Show, and NonEmptyParallel. It seems to also have TraverseFilter, but I don't know if that's only for binary compatibility or if it would be fine to add a new instance of that anyway.
