another addition to notification node

I'm checking this feature on my project
Here it's new node format
```bash
rx  <notification from="6285643077444-1407855840@g.us" id="411519711" participant="6285643077444@s.whatsapp.net" type="participant" t="1408351470" notify="Ardian Yuli">
rx    <add jid="6289631037444@s.whatsapp.net"></add>
rx  </notification>


rx  <notification from="6285643077444-1407855840@g.us" id="1857557342" participant="6285643077444@s.whatsapp.net" type="participant" t="1408351484" notify="Ardian Yuli">
rx    <remove jid="6289631037444@s.whatsapp.net" author="6285643077444@s.whatsapp.net"></remove>
rx  </notification>
```
