Set Rounded Corners on Rectangle

[seanlynchwv]

Description

It's now possible to set the radius to create rounded corners on rectangle shapes.

        $panel = new AutoShape();
        $panel->setType(AutoShape::TYPE_ROUNDED_RECTANGLE)
            ->setOffsetX($x)
            ->setOffsetY($y)
            ->setWidth($w)
            ->setHeight($h)
            ->setRoundRectCorner(4); // new

Previously the corners were hard coded to a large value making custom designs difficult.

Hey @Progi1984

CI passes on PHP 7.1 and 7.4+ but fails on 7.2–7.3 because, as far as I can tell, the allowed phpoffice/phpspreadsheet versions (^1.9–^5.0) no longer include any release compatible with PHP 7.2/7.3.

For the next major release 1.3.0, could we set php 7.4 as the new minimum? PHP 7.4 reached EOL on November 28, 2022.
