Compilation warnings on Elixir 1.13

[kuroda]

Compiling ssh_client_key_api with Elixir 1.13.1 (compiled with Erlang/OTP 24) gives the following warning:

warning: :public_key.pem_decode/1 defined in application :public_key is used by the current application but the current application does not depend on :public_key. To fix this, you must do one of:

  1. If :public_key is part of Erlang/Elixir, you must include it under :extra_applications inside "def application" in your mix.exs

  2. If :public_key is a dependency, make sure it is listed under "def deps" in your mix.exs

  3. In case you don't want to add a requirement to :public_key, you may optionally skip this warning by adding [xref: [exclude: [:public_key]]] to your "def project" in mix.exs
