feature: add communication->agenda

[Vexcited]

There's two different views : one per week and one in chronological order.

Even though, we might think it's two different requests, it's only one !

When looking closely, we have

{"session":6793835,"numeroOrdre":"b24fe5eed2fdf9111af9b9dd64b92ff2","nom":"PageAgenda","donneesSec":{"_Signature_":{"onglet":9},"donnees":{"NumeroSemaine":0,"AvecListeClasses":true}}}

as payload and NumeroSemaine is where we should start getting the agenda.

Returned items are all from NumeroSemaine until the end of year(?)
