The Warmup will now recursively handle interface and their class
implementations. It is also done in a more clever way: instead of
warming up all properties and constructors, it takes only what is
needed.
This new method can be used for instance in a pipeline during the build
and deployment of the application.
The cache has to be registered first, otherwise the warmup will end up
being useless.
```php
$cache = new \CuyZ\Valinor\Cache\FileSystemCache('path/to/cache-dir');
$mapperBuilder = (new \CuyZ\Valinor\MapperBuilder())->withCache($cache);
// During the build:
$mapperBuilder->warmup(SomeClass::class, SomeOtherClass::class);
// In the application:
$mapper->mapper()->map(SomeClass::class, [/* … */]);
```

When the application runs in a development environment, the cache
implementation should be decorated with `FileWatchingCache` to prevent
invalid cache entries states, which can result in the library not
behaving as expected (missing property value, callable with outdated
signature, …).
```php
$cache = new \CuyZ\Valinor\Cache\FileSystemCache('path/to/cache-dir');
if ($isApplicationInDevelopmentEnvironment) {
$cache = new \CuyZ\Valinor\Cache\FileWatchingCache($cache);
}
(new \CuyZ\Valinor\MapperBuilder())
->withCache($cache)
->mapper()
->map(SomeClass::class, [/* … */]);
```
This behavior now forces to explicitly inject `FileWatchingCache`, when
it was done automatically before; but because it shouldn't be used in
a production environment, it will increase overall performance.
The cache implementation that was previously injected in the mapper
builder must now be manually injected. This gives better control on when
the cache should be enabled, especially depending on which environment
the application is running.
The library provides a cache implementation out of the box, which saves
cache entries into the file system.
It is also possible to use any PSR-16 compliant implementation, as long
as it is capable of caching the entries handled by the library.
```php
$cache = new \CuyZ\Valinor\Cache\FileSystemCache('path/to/cache-dir');
(new \CuyZ\Valinor\MapperBuilder())
->withCache($cache)
->mapper()
->map(SomeClass::class, [/* … */]);
```
