* Automated Transfer processors
This PR introduces a few things:
* Payouts can now be directly nested under a store instead of through a pull payment.
* The Wallet Send screen now has an option to "schedule" instead of simply creating a transaction. When you click on schedule, all transaction destinations are converted into approved payouts. Any options relating to fees or coin selection are discarded.
* There is a new concept introduced, called "Transfer Processors". Transfer Processors are services for stores that process payouts that are awaiting payment. Each processor specifies which payment methods it can handle. BTCPay Server will have some forms of transfer processors baked in but it has been designed to allow the Plugin System to provide additional processors.
* The initial transfer processors provided are "automated processors", for on chain and lightning payment methods. They can be configured to process payouts every X amount of minutes. For on-chain, this means payments are batched into one transaction, resulting in more efficient and cheaper fees for processing.
