Pay - Sardine NFT Checkout - ERC1155 Primary Sales

[BellringerQuinn]

Expose the ability to purchase an ERC1155 using our Primary Sales contracts via a credit card with Sardine - this is a web based purchase flow

Ridl: https://github.com/0xsequence/stack/blob/master/api/proto/api.ridl#L869
Specifically, we'll need to integrate every endpoint that wasn't added in #287

At a high level, Sardine will be given minting privileges on each whitelisted primary sales contract (notice: your contract needs to be whitelisted; it is recommended to use the same config as done in Unity test for testing) and when doing the checkout we include the calldata for minting a token and our sales contract which they will sign and send as a transaction after our credit card purchase is confirmed
It is recommended to expose an interface that makes this logic (assembling calldata) much easier or at least clearer; please reference the Unity code for inspiration
