How to find out if TrueLayer supports a particular sort code for pay-in?

If you have a customer's sort code and want to know whether you can offer them an option to pay in using TrueLayer or not, you would need to know if the customer sort code maps to one of the supported TrueLayer banks from the /providers endpoint. 

Steps

• Use an external API to find out the bank related to a particular sort code. Example: Sort Code Checker informs that 04-00-04 belongs to Monzo Bank.
• Match the output of that external API (ie. bank name) against the provider_ids we provide (eg. ob-natwest).
