iex> SecretsWatcherFileSystem.subscribe(pid)

iex> SecretsWatcherFileSystem.start_link(dirs: ["/path/to/some/files"], latency: 0)

iex> SecretsWatcherFileSystem.start_link(backend: :fs_mac, dirs: ["/tmp/fs"], name: :worker)
iex> SecretsWatcherFileSystem.subscribe(:worker)

{:file_event, worker_pid, :stop}
