also we don’t have traverses for nullables? is this expected?

e.g.

inline fun <A, B> Iterable<A>.traverseNullable(fn: (A) -> B?): List<B>? = ...

or

inline fun <A, B, C> Either<A, B>.traverseNullable(fn: (B) -> C?): Either<A, C>?

happy to raise a PR for those if they are fine from Arrow crew’s perspective
