  A module that implements the ERTSResolver behaviour is responsible for returning a target with
  a fully resolved `:erts_source` field.

  You can register your ERTS resolver as the default one by calling `Burrito.register_erts_resolver/1`,
  otherwise Burrito will use the `Burrito.Util.DefaultERTSResolver` module.
