Add tuple generator

[mtk3d]

Hello 😄
I prepared my proposal of Tuples with generics, as discussed in here #38
It's just proposal, still in progress, there is no tests yet.

I started by just coding this classes manually, but making them manually without mistakes is hard, and laborious. So following vavr's approach, I built a template with command that generates the code of the Tuples.
I'm not 100% contented by this solution, but that's the fastest and lightest solution that came to my mind.

I'm also wondering about using library like https://github.com/nette/php-generator. I could install it as a dev dependency and use it to generating the code in object oriented way, and it could be more readable maybe 🤔

@akondas What do you think about that?

I've replaced it with better implementation using nette/php-generator. It works ways better in my opinion.
There is a test that is testing first 3 classes of Tuples by comparing strings, but I wrote them only in development purpose. In final implementation that doesn't make sense to keep them. Better will be to test only their behaviors and php-cs-fixer will check the code style.
It's still in progress and require a lot of refactoring.

Todo:

• Make some maintenance on master branch, do decrease size of PR Update dev dependencies #77
• More test coverage for TupleN classes
• Generator command CI checker, to avoid manual changes in generated classes

Ok, I belive I'm done. ~1300 lines of the PR is generated automatically, but it's still quite big, sorry for that 😄

I've added validation command to composer tests which is validating if existing Tuples has been generated by latest version of generator.
I covered Tuples in 100% in tests what I believe is quite important for generated classes.

looks cool, are you happy to rebase and wait for php 8.2 upgarde?

Yes, thank you! 😄
I've refactored generate command a little bit. Right now it's a single command to validate and generate and it shows diff if validation fails:

I'm not against it, but couldn't we use temp dir?

Hey @mtk3d, Is there anything left to do here, because I would like to give it a chance, it's a big PR and I think it would be a pity to leave it open :)

[akondas]

Hi @mtk3d, ping again, If you don't have time right now, I can fix the changes after rebase and do a merge.
