Describe the bug

The fetchPaymentMethodNonces method in BTAPIClient always returns the nonce in the "Unknown" type.

Root cause: After the SDK migrated to Swift. The jsonParsingBlocks in BTPaymentMethodNonceParser is not get registered with different types.

To reproduce

1. Call fetchPaymentMethodNonces in BTAPIClient when there are saved nonce.
2. Debug the nonce values. (Check the screenshot)

Expected behavior

1. The SDK should behave as the Objective-C version
2. The nonce type should be the correct type.

In the Objective-C version of the SDK, the parsing blocks are registered in +load, as you can see in the below image. But I don't see this registered anywhere in the Swift version.

Hello @haojin2020 -

Thanks so much for reporting this issue! I was able to reproduce the behavior you are seeing and this is certainly a bug introduced in v6. I've opened PR #1100 to resolve this issue on our side. Please feel free to pull down that branch to ensure things are working as expected now on your side.

🤔 we may actually have to get creative with our solution since the load method does not exist in Swift. Right now some of the types work as expected but for example the credit card types aren't passed through as expected. We will dig into this a bit more and come up with a solution that can work in the same way it did in Obj-C. Thanks again for bringing this to our attention.
