New release: https://github.com/phpbench/phpbench/releases/tag/1.3.0

This release contains some minor features, bug fixes and many improvements to type coverage thanks to Andrew Ivchenkov

I've released PHPBench 1.2.15 which:

- Drops support for PHP < 8.1
- Supports Symfony 7

https://github.com/phpbench/phpbench/releases/tag/1.2.15

I've dropped support for PHP < 8.1 on the master branch, and everything seems to be fine with PHP 8.3. Will hopefully make a few iterations to upgrade the code base (which was supporting 7.4) over the next days before releasing.
