Issue with Clojure 1.8.0-alpha2 Tuples

When trying our core.rrb-vector with the latest Clojure 1.8.0-alpha2 I see the following error:

Exception in thread "main" java.lang.IllegalArgumentException: No implementation of method: :slicev of protocol: #'clojure.core.rrb-vector.protocols/PSliceableVector found for class: clojure.lang.Tuple$T0, compilingmikera/timeline/examples.clj:12:1)

I believe the cause of this is the new Tuple types. core-rrb-vector should ideally be able to handle this like any other IPersistentVector instance, but it does not currently seem to be able to do so.
