Add PHPUnit 9 support

[steve-todorov]

Hi there,

I'm using this dependency and was wondering if there are plans for PHPUnit 9 support?
It looks like in PHPUnit 9 the PHPUnit\TextUI\ResultPrinter class has been converted into an interface (check sebastianbergmann/phpunit#4024) and there is now a PHPUnit\TextUI\DefaultResultPrinter

So the fix to the issue would be simply to change this part:

phpunit-detailed-printer/src/Printer.php

Lines 3 to 11 in ae5ab59

	namespace LimeDeck\Testing;
	use PHPUnit\Framework\Test;
	use PHPUnit\Framework\Warning;
	use PHPUnit\TextUI\ResultPrinter;
	use PHPUnit\Util\Test as UtilTest;
	use PHPUnit\Framework\AssertionFailedError;
	class Printer extends ResultPrinter

to this:

namespace LimeDeck\Testing;

use PHPUnit\Framework\Test;
use PHPUnit\Framework\Warning;
use PHPUnit\TextUI\DefaultResultPrinter;
use PHPUnit\Util\Test as UtilTest;
use PHPUnit\Framework\AssertionFailedError;

class Printer extends DefaultResultPrinter
{
...
}

Hey @steve-todorov, thanks for reporting. Since you've already got this figured out, could you please create a PR? We could release a major version of this to be able to support PHPUnit 9.

Thank you!

I've just pushed my changes. Tests are passing on my end but it looks like there's no CI hooked?
