Add support for PHP 8

[S1SYPHOS]

Hey there,
since my upgrade to PHP 8 I get this when updating via composer:

biblys/isbn 2.4.0 requires php ^7.1 -> your php version (8.0.8) does not satisfy that requirement.

Please upgrade your composer.json accordingly, see #36

Thanks!

Hey @S1SYPHOS, I don't plan to support before the next major version of this library, because PHP 8.0 support requires to remove deprecated code, but I will try to release a 3.0 beta version as soon as possible.

[S1SYPHOS]

Thanks very much for letting me know - in the meantime, I'll go full risk with --ignore-platform-reqs 🦊

You can now install the 3.0 beta version, supporting PHP 8, using the next branch:
https://github.com/biblys/isbn/tree/next

I'll keep this issue open until 3.0 is released and PHP 8 officially supported.

It might be easier to release the next branch as 3.0.0-beta.1 pre-release, though .. this might help mitigate Composer complaining about minimum stability. Could you give an estimate when v3 will be released? Maybe I can help move things along ✌️

// Edit: I just had a look at the 'roadmap' board, I'll see if I can whip up something!

Hey @S1SYPHOS, I've just released a 3.0.0-alpha.1 version (as development is still in progress, it's more an alpha than a beta) based on the next branch.

I didn't work a lot on this library for the past few months due to lack of motivation, but I can find some if I know others users are bothered by the current state of the project (I'm still struggling to update to PHP 8 on my main project, hence the lack of motivation).

Please tell me if you have any question about the roadmap (the discussion section should be great for that).

Today I tried nicebooks/isbn which works very good and has full PHP v8 support 😕

No hurt feelings, if it better suites for your use case, go for it! And thanks again for you contributions 🙂

You can use Rector to move to PHP 8.0 or even 8.1.

Thanks @ph-il 😀
