A little improvement idea to the foundry raffle game

[OxSmartBlock]

The current version of the foundry raffle contract allows an address to enter the raffle contest multiple times which can allow such address in different index in the players array . I think there should be check to allow an address enter raffle just once or we basically don't append the address to array list just accept their deposit into the contract .

Hello @OxSmartBlock, I think it is a Design choice. They are paying to reserve more slots. If they are paying only once to reserve multiple slots then that will be a serious concern.
