Release 8.1

Core:

• Chain an immutable, efficient, scalable, concatenatable List.
• BiCollectors.partitioningBy()
• MoreCollectors.collectingAndThen() to be used together with partitioningBy(). For example:

   collectingAndThen(
       partitioningBy(Person::isGood), (good, evil) -> ...)

• BiCollectors.collectingAndThen()
• BiCollectors.inverse()
• Optionals.inOrder() to help reducing nesting.
• Fanout for easy structured concurrency.
