Aggregate refined

I just noticed that the new finch-refined module wasn't being published.

Oh that's a good catch. Thanks @rider-yi!

CI fails with the following error on 2.11:

/home/travis/build/finagle/finch/refined/src/main/scala/io/finch/refined/package.scala:12:88: value toOption is not a member of Either[String,F[A,B]]
[error]   ): DecodePath[F[A, B]] = DecodePath.instance(s => ad(s).flatMap(p => rt.refine[B](p).toOption))

Do you have any idea why? I restarted the job just in case.

@vkostyukov I think its Scala 2.11 v 2.12 related. Pretty sure Either doesn't have toOption in Scala 2.11. Cats has an implicit syntax for it. We'll either have to use that or manually fold the Either here.

I see. Sounds like we never compiled it for 2.11 hence never saw an error. Importing Cats' syntax works for me, fwiw. @rider-yi any chance you want to fix this as part of this PR?

I just fixed the error with RightProjection. It seems that importing Cats's syntax causes unused warning:

[warn] /Users/yu_ishikawa/finch/refined/src/main/scala/io/finch/refined/package.scala:3:27: Unused import
[warn] import cats.syntax.either._
[warn]                           ^

Changes look good to me! Thanks again, @rider-yi!
