Custom styles can not have style modifiers set in any order as advertised

Example:

```php
\Ahc\Cli\Output\Color::style('alert', ['fg' => Ahc\Cli\Output\Color::YELLOW]);
$writer = new Writer();

// This works
$writer->alertBold('alert');
$writer->colors('<alertBold>alert</end>');

// Currently doesn't work
$writer->boldAlert('alert');
$writer->colors('<boldAlert>alert</end>');
```
