Requiring enfocus.macros under Clojure 1.10 and above triggers an error

[zane]

enfocus.macros appears to have a malformed :import in its ns form. This results in an error when it is required from versions of Clojure that enforce the ns macro's spec.

I believe this could be fixed by the following change:

- (:import [org.jsoup.Jsoup]))
+ (:import [org.jsoup Jsoup]))

If that looks good I'd be happy to submit a pull request. Just let me know!

Reproduction steps

With the clojure command line tools installed:

clojure -Srepro -Sdeps '{:deps {org.clojure/clojure {:mvn/version "1.10.0"}, enfocus {:mvn/version "2.1.1"}}}' -e "(require 'enfocus.macros)" 

Expected results

clojure exits without triggering an error.

Actual results

Exception in thread "main" Syntax error macroexpanding clojure.core/ns at (enfocus/macros.clj:1:1).
Call to clojure.core/ns did not conform to spec.
