Draft: recurring-transfer

Add pallet recurring-transfer for allowing on-chain recurring transfers.

Il y a encore plein de bouts inutiles de la palette template, je les enlèverai progressivement.

@librelois Il y a une erreur qui me bloque :

66 |     #[pallet::storage]
   |               ^^^^^^^ the trait `std::default::Default` is not implemented for `T`

Avec une aide amusante :

help: consider further restricting this bound
   |
33 | #[frame_support::pallet] + std::default::Default
   |                          ^^^^^^^^^^^^^^^^^^^^^^^

requested review from @librelois

Puisqu'il n'y a pas encore de CI je mets toute la sortie du compilateur ici :

@tuxmain dans un premier temps ne modifie pas les runtime stp, ou seulement le runtime gdev, c'est suffisant pour tester en réel :)

Ton erreur viens du fait que Derive(Default) ne fonctionne qui si tout les génériques impl Default. Deux solutions:

1. impl Default à la main
2. Utiliser OptionQuery au lieu de valueQuery, je te recommande ce choix, ça permet de ne pas avoir besoin de Default.

Aussi j'ai regardé vite fait en diagonale ton code, il faut que tu utilise les génériques BlockNumber et Balance et non pas des u32 directement ;)
