Add call_function!/3 - Githubissues

Adds a new API function call_function!/3 which executes Lua functions inside the passed environment. Allows for calling functions by keys (fully qualified name), references, and direct function callbacks

Also adds the encode!/1 function for encoding values

Usage

defmodule MyAPI do
  use Lua.API, scope: "example"

  deflua foo(value), state do
    Lua.call_function!(state, [:string, :lower], [value])
  end
end

lua = Lua.new() |> Lua.load_api(MyAPI)

{["wow"], _} = Lua.eval!(lua, "return example.foo(\"WOW\")")
