Adapt cl-format and/or wrap goog.string/format

[jaidetree]

It is convenient when working with Clojure being able to just call (printf "%s = %s" "some-var" some-var). Perhaps nbb can provide a cl-format and printf implementations lazily from modules?

Based on what we discussed in Slack we could offer both but ideally they should be lazy so as not to slow down runtime.

Willing to draft a PR but what were you thinking as far as modules and file-names?
