Feature Request: function for generating idempotency_key

[TimBHowe]

The issue:
We have a site using the WooCommerce Square plugin for a payment gateway that utilize the WooCommerce Plugin Framework. There appears to be an issue where the plugin is using function get_order_with_unique_transaction_ref from wc-plugin-framework/woocommerce/payment-gateway/class-sv-wc-payment-gateway.php to set it's idempotency_key causing double charging in case of false error responses.

Feature Request
We suggest adding a function to the frame work to idempotency_key that can be used by payment gateways that support them such as Square.

Hey
Been trying to fix the following issues in the WooCommerce Square plugin which uses this plugin framework and thought it would be good to include the generating of an idempotency key here so it can be used in other framework to fix the 2 general problem

I believe this is still an relevant to add to help payment gateway plugin that use the framework. Unfortunately, I have not had a chance to revisit it
