The method `MapperBuilder::bind()` can be used to define a custom way to
build an object during the mapping.
The return type of the callback will be resolved by the mapping to know
when to use it.
The callback can take any arguments, that will automatically be mapped
using the given source. These arguments can then be used to instantiate
the object in the desired way.
Example:
```php
(new \CuyZ\Valinor\MapperBuilder())
->bind(function(string $string, OtherClass $otherClass): SomeClass {
$someClass = new SomeClass($string);
$someClass->addOtherClass($otherClass);
return $someClass;
})
->mapper()
->map(SomeClass::class, [
// …
]);
```
