New dbg/2 function

Andrea Leopardi from the Elixir Core team recently introduced a new debug feature in Elixir 1.14+.

  "Example"
  |> String.upcase()
  |> String.split("")
  |> Enum.shuffle()
  |> dbg()

When running this code, the pipeline will stop at each step.

  pry(1)> next
  "Example" #=> "Example"
  pry(1)> next
  |> String.upcase() #=> "EXAMPLE"
  pry(1)> next
  |> String.split("") #=> ["", "E", "X", "A", ...]
  pry(1)> next
  |> Enum.shuffle() #=> ["M", "X", "L", "P", ...]
  :ok
