Support of PHP versions?

[stephanvierkant]

I see this library still supports PHP 7.1, which is End of Life (EOL) for a long time. Even 7.3 is EOL as of today.

What's the policy about PHP support? The only supported versions are 7.4, 8.0 and 8.1

In my opinion libraries should drop support of PHP versions that are end of life, because it makes contributing to this library much easier.

Sure, if there is code that is obsolete in current LTS PHP versions, and that it is needed to drop it somehow, we can drop it and release a new major version of this library
