Hi everyone, here's my attempt to add clojure CLI and babashka support for ob-clojure.el

- Adds a header parameter to override org-babel-clojure-backend
- Adds :args param (right now only used for clojure-cli)

I have tested it with these minimal cases:

#+begin_src clojure :backend clj-cli :args "-Sdeps '{:deps {inflections {:mvn/version \"0.13.2\"}}}'"
  (use 'inflections.core)
  (plural "word")
#+end_src

#+begin_src clojure :backend babashka :results output
  (range 10)
#+end_src

Please let me know what you think. Any advice is appreciated, since I have never contributed before. Thank you.
