Prefer Kotlin nullable syntax inside either DSL, or replace with explicit fold

Replace with

import arrow.core.right

fold({ emptyList() }, { iterable -> iterable.map { it.right() } })

fun <A, B> Ior<A, Option<B>>.~~sequenceOption~~(): Option<Ior<A, B>>

fun <A, B> Validated<A, Option<B>>.~~sequenceOption~~(): Option<Validated<A, B>>

fun <K, V> Map<K, Option<V>>.~~sequenceOption~~(): Option<Map<K, V>>
