Add split primary sale & royalty payments

Allow the ability to add 2 or more ETH wallets to a sale item with the ability to split payments for both primary sales and royalty payments. i.e,

PRIMARY PAYMENT: Wallet 1: 0x5fw............dw1s : 50% (Minting Wallet) Wallet 2: 0xahe............22an : 40% Wallet 3: 0xdd8............uxxf : 10%

ROYALTY PAYMENT: Wallet 1: 0x5fw............dw1s : 10% (Minting Wallet) Wallet 2: 0xahe............22an : 2.5% Wallet 3: 0xdd8............uxxf : 0%

This will help with help with any collaborations and negate any administration issues with sale payments.

At very least being able to add one other wallet for split payments would be fantastic.

Not sure how to negate subsequent gas fees, L2 perhaps? But that's what a rad Dev team are employed for. Blockchain tech is made for this.
