A mailto hyperlink emits the url text instead of the hyperlink in Html output

- [X] a bug report
- [ ] a feature request
- [ ] **not** a usage question (ask them on https://stackoverflow.com/questions/tagged/phpspreadsheet or https://gitter.im/PHPOffice/PhpSpreadsheet)

Setting a mailto hyperlink on a cell replaces the cell contents with the mailto url when writing HTML.

The bug appears to be this line in Html.php:

if ($parseScheme === 1 && !in_array($matches[1], ['http', 'https', 'file', 'ftp', 's3'], true)) {

The problem is corrected by adding mailto to the list of url schemes:

if ($parseScheme === 1 && !in_array($matches[1], ['http', 'https', 'file', 'ftp', 's3','mailto'], true)) {

What is the expected behavior?

Output:

Mail Me!

What is the current behavior?

Outputs:

mailto:me@example.com

What are the steps to reproduce?

$worksheet->setCellValueByColumnAndRow(1, 1, 'Mail Me!');

$worksheet->getCell('A1')->getHyperlink()->setUrl('mailto:me@example.com');

$writer = PhpOffice\PhpSpreadsheet\IOFactory::createWriter($spreadsheet, 'Html');
