Changes proposed in this Pull Request:

Integration with the Aelia Currency Switcher, for multi-currency support. We proposed the same integration a few months ago to Sau/Cal, but it hasn't been added to the Amazon Pay plugin, yet.

How to test the changes in this Pull Request:

1. Install and configure the Aelia Currency Switcher (free copy available on request), enabling multiple currencies.
2. Go to WooCommerce > Settings > Payments > Amazon Pay.
3. Verify that the integration is active (see https://prnt.sc/10d2jg0).
4. Enable Amazon Pay for some currencies in the gateway settings.
5. Enable Amazon Pay for the same currencies at WooCommerce > Currency Switcher > Payment Gateways (see https://prnt.sc/10d2izo).
6. Place an order in the enabled currencies, paying with Amazon. and verify that it's processed correctly.

@kalessil I received a notification that this PR has been closed, but it doesn't look like it was merged. Was it closed by mistake?

Note: the PR b553602, referenced in the closure note, mentions this request, but it's not related to it. That PR refers to WCML, which is a different plugin, and not related to the Aelia Currency Switcher, for which I submitted my PR.

@kalessil @msaggiorato Just a ping to remind that this PR has been closed without a merge. The PR that claims to have closed it is unrelated to the changes in this one.
