Can't encode SubVector

[catharinejm]

repl=> (clj->cljson (subvec [1 2 3 4] 0 2))
IllegalArgumentException No cljson encoding for '[1 2]'.  tailrecursion.cljson/encode (cljson.clj:72)

Looks like clojure.lang.PersistentVector is extended with EncodeTagged, but not clojure.lang.IPersistentVector. In my (extremely rudimentary) testing, making it IPersistentVector instead seems to work fine.

Good catch!

Trolling around clojure.lang.RT and clojure.lang.APersistentVector$SubVector, it looks like what we want is to add an implementation for instances of clojure.lang.APersistentVector, or possibly check for APersistentVector instead of PersistentVector.

Using IPersistentVector works, but we want to avoid interfaces if we can because they might overlap.
