Pilot for naive approach to accept compilations by command line

• Accepts compiler.command on plugin options
  • The option expects a function which takes targets: string[] and returns a command to show compilation's result in stdout

  • { compiler: { command: (targets) => `npx elm-optimize-level2 -O3 --output elm.js ${target[0]} > /dev/null && cat elm.js`
    

• Update devDependencies
