CryptoOnramp SDK: Example App - Adds "Instant" and "Standard" ACH Settlement Speeds

[Twigz]

Summary

When making a payment by bank account, the example app now provides an option between instant or standard ACH settlement speeds. We default to instant for all other payment types.

Motivation

1. We were asked in this thread of our shared channel.
2. Docs for new parameter.

Testing

1. Tested with an existing bank account payment token and new bank account to make sure the ACH settlement speed option appeared.
2. Upon creating the session, made sure that the processing time matched the option selected on the previous screen.
3. Also ensured that credit card and apple pay options did not show the ACH settlement speed option, and defaulted to instant.
4. Inspected the requests to make sure the parameter looked correct:
