Integrating with Clay and data visualisation tools

Placing the following code in .lnvim.fnl with Olical/nvim-local-fennel installed will give you the <localleader>ev mapping in Clojure buffers. This allows you to send the root form under your cursor to Clay for rendering. Additionally <localleader>env will let you render the current namespace
