feat: option to generate code with strict types

[MrMeshok]

PHP, by default, will coerce values of the wrong type into the expected scalar type declaration if possible. This leads to unexpected behavior. For example, losing decimal digits when casting float to int

readonly class IntDto
{
    public function __construct(
        public int $var,
    ) {}
}

$autoMapper = \AutoMapper\AutoMapper::create();
$result = $autoMapper->map(['var' => 1.1111], IntDto::class);
$result->var; // var is 1

This PR adds configuration to add declare(strict_types=1) to generated code when mapping, so instead of unexpected behavior, you get TypeError.

If everything is ok, I will update the docs, but I am not very fluent with english, so maybe someone else could write a more understandable description.

👍 for this thanks, can you add the possibility to configure this through the Mapper attribute also ?

Also wondering if declare strict should be true by default ? poke @Korbeil @nikophil ?

If you could update the doc and add a note in the changelog it would be nice, if you are not comfortable doing so we can do it.

[Korbeil]

I'm totally for this option and I think we should put it by default as @joelwurtz stated.
Same as he said, we would require a configuration on the Mapper attribute 🙏

[nikophil]

won't we face some BC break if this becomes a default thing?

[MrMeshok]

Made it configurable from Mapper and enabled by default. I'll wait for the decision about the default value and force push if it needs to be changed. I will leave the changelog and docs for you

[MrMeshok]

Seems like readonly was missed here

[Korbeil]

won't we face some BC break if this becomes a default thing?

This is right, we should put it disabled by default and we will put it enabled by default on next major ~
Could you make the change @MrMeshok ? 🙏

[MrMeshok]

@Korbeil Done👍

[Korbeil]

Looks good to me 👌

Could you add a note about your feature into the CHANGELOG please ?

[MrMeshok]

Added note to CHANGELOG and combined everything in 1 commit

[Korbeil]

Thanks for the feature @MrMeshok ! 🙏
