This modules provides a low-level interface for interacting with the wpa_supplicant

Example use:

iex> {:ok, ws} = VintageNetWiFi.WPASupplicantLL.start_link(path: "/tmp/vintage_net/wpa_supplicant/wlan0", notification_pid: self())
{:ok, #PID<0.1795.0>}
iex> VintageNetWiFi.WPASupplicantLL.control_request(ws, "ATTACH")
{:ok, "OK
"}
iex> VintageNetWiFi.WPASupplicantLL.control_request(ws, "SCAN")
{:ok, "OK
"}
iex> flush
