Incorporate Clojure 1.12 changes

[seancorfield]

Several new namespaces were added in 1.12

Also in clojure.core since 1.12 there's add-lib and add-libs. Example:

user=> (add-lib 'dev.weavejester/medley)
[dev.weavejester/medley]
;; or
user=> (add-lib 'dev.weavejester/medley {:mvn/version "1.8.1"})
[dev.weavejester/medley]
user=> (require '[medley.core :as medley])
nil
user=> (medley/partition-between (fn [prev-item item] (< prev-item item)) [1 1 2 3 2])
((1 1) (2) (3 2))

;; Or multiple at once
user=> (add-libs '{dev.weavejester/medley {:mvn/version "1.8.1"} 
                   metosin/malli {:mvn/version "0.16.4}})
[borkdude/dynaload borkdude/edamame fipp/fipp metosin/malli mvxcvi/arrangement
 org.clojure/core.rrb-vector org.clojure/test.check org.clojure/tools.reader]

There's also an implementation for Leiningen available via the library lein-add-libs.

Those new functions are not in clojure.core. They are referred in from https://clojure.github.io/clojure/clojure.repl-api.html#clojure.repl.deps

Aah oops 😳. Thanks for clarification.
