plugin: generate diagrams from PlantUML code

[practicalli-johnny]

Generate a UML diagram from PlantUML code within a Clojure file.

NOTE: no specific Neovim plugin is required, as PlantUML can be called from a Neovim key mapping

Create a <leader>lu key mapping to launch PlantUML (using OS exec path or specifying location of plantuml binary)
