Subject: simtech: handle non-standard '+CRING' URCs

The SIM7600E ends up emitting these URCs with too many <CR>s, and the
generic +CRING handler doesn't catch them, interfering with other
actions, e.g.:

  $ sudo mmcli --call 1 --accept
  error: couldn't accept the call: 'GDBus.Error:org.freedesktop.ModemManager1.Error.Core.Failed: Couldn't accept the call: Unhandled response '+CRING: VOICE

  +CRING: VOICE''
