Misc fixes

Somehow got left off previous PR.

PHP 8.1 release for legacy apps

You are advised to switch to https://github.com/academe/opayo-pi which replaces this package. In the meantime, if you are still planning a migration, but need to move to PHP 8, then this release should see you okay.

Multiple fixes. additions and some refactoring

Quite a few changes here (should have made a release six months ago really) so test thoroughly:

• Issue #11 Handle Card Tokens
• Issue #40 Add Refund support
• Issue #43 3D Secure object structure fix
• Issue #44 Add void support
• Issue #45 Some general restructuring
• Issue #47 Support saved cards
• Issue #48 Expand supported currencies
• Issue #50 RepeatPayment supports giftAid option
• Issue #51 mathiasverraes/money is abandoned
• Issue #53 Support Deferred transaction type and abort/release instructions
• Issue #54 Is Academe\SagePay\Psr7\Response\Model\Amount used?

From now on, I'm going to be writing unit tests for any functions that are being modified to help try to keep this package stable.

Support Repeat Transactions

Quite a bit of refactoring, but the interfaces are essentially the same.

First release

Should all be functional now. Covers only the back-end, so handle all the front end functionality as recommended by Sage Pay.
