MapEntry in ClojureScript requires a third argument "__hash"

[w9]

https://github.com/cloojure/tupelo/blob/63a34492bdb2d1f7a94050c653ee233ec1211380/src/cljc/tupelo/core.cljc#L1207

See https://cljs.github.io/api/cljs.core/MapEntry

Currently, the missing third argument gives a warning when compiled:

------ WARNING #1 - :fn-arity --------------------------------------------------
 Resource: tupelo/core.cljc:1200:12
 Wrong number of args (2) passed to cljs.core.MapEntry
--------------------------------------------------------------------------------

Hmmm,

Looks like we could fix with this as the 3rd arg:

(hash-ordered-coll [key val])

???

Since __hash is mutable and filled in later, nil might work better as the 3rd arg.

Or even (first {k v}) might be a portable solution.
