New

• #112: Add binding, with-out-str and with-in-str:

$ ./bb '(let [w (java.io.StringWriter.)] (binding [*out* w] (println "hello")) (str w))'
"hello\n"

$ ./bb "(count (with-out-str (println \"hello\")))"
6

$ ./bb '(with-in-str "hi" (read-line))'
"hi"

Notes:

• Currently binding only works with clojure.core/*in* and clojure.core/*out*
• *in* has a special meaning in babashka expressions, but you can refer to Clojure's *in*by fully qualifying it: clojure.core/*in*.
