Minimum changes to prevent deprecated messages in PHP 8.1

[mmenavas]

Overview

This PR adds return types to the methods in src/Table.php that override the Iterator class. This is necessary because PHP 8.1 requires "overriding methods to declare a compatible return type".

Fixes #70.

The tests are failing, but not due to your changes.

Give me the weekend and I will modify the Github Actions to fix the issues.

Hi @courtney-miles @mmenavas - hoping to use this library in a project soon and wondering where things stand with PHP 8.1 - happy to help if I can.

Hi @dafeder! Once this PR is merged, we'll be compatible with PHP 8.1 and 8.2.

@courtney-miles Since the changes on this PR will require dropping support for earlier versions of PHP (PHP <= 8.0), would it be possible to maintain a 1.x version and a 2.x version where the former will continue to support older versions of PHP and the latter 8.1+?

It appears this PR is no longer needed as of 1.2.0 release?
