Paraunit 1.2.0: PHP 8 & PHPUnit 9.3 support

This release contains only support for newer versions of PHP & PHPUnit; due to PHPUnit 9.3 requiring a new major version of phpunit/php-code-coverage, I’m forced to drop support to all PHPUnit versions below 9.3. Usage of Paraunit is unchanged.

Here’s the full changelog of the release:

Added

• Add support for PHP 8.0 #154
• Add support for PHPUnit 9.3 #153

Removed

• Drop support for PHPUnit < 9.3 #153
