TYPO3 v13 compatibility

This release comes with support for TYPO3 v13. It contains only one breaking change, which is documented below.

[!!!][TASK] Remove devlog extension setting #63

The devlog setting has been removed without replacement. The extension still logs debug events, but a logfile must now be configured manually in additional.php if required.

$GLOBALS['TYPO3_CONF_VARS']['LOG']['Derhansen']['SfYubikey']['writerConfiguration'] = [
    \TYPO3\CMS\Core\Log\LogLevel::DEBUG => [
        \TYPO3\CMS\Core\Log\Writer\FileWriter::class => [
            'logFile' => 'typo3temp/var/log/sf_yubikey.log',
        ],
    ],
];
