Target PHP 8 in composer.json

Add support to PHP 8

composer.json looks good, but composer.lock is outdated, could you update that?

Also it looks like there is more to be updated. When I just tried to run it on PHP 8 nothing happened. So this would be a first step to PHP 8 support tbh

Looking at the error message on all travis jobs, this composer.lock file is not up to date with composer.json. For example: https://travis-ci.com/github/WyriHaximus/reactphp-child-process-pool/jobs/460266452#L216

Can you fix that?

Thanks for the update, at least it installs now on PHP 7.x.

On PHP 8.x (nightly) it can't because not all dependencies have been updated yet to support PHP 8. So at least https://github.com/WyriHaximus/reactphp-child-process-messenger has to be updated. Already working on the CPU core count detector. Maybe one or two more packages also need updates before this one also works.

Note that this only unlocks future PHP 8 support in this package, dependencies are as good as ready to be tagged with PHP 8 support, and thus this package should also have it very soon.
