[Bug] Not all directories are cached correctly, as well as the laravel-data directory.

[SanderSander]

The command data:cache-structures doesn't cache all Data objects correctly when using for example vendor paths, or paths outside the application

The current config doesn't allow to define the correct root_namespace and base_path per directory when using multiple directories.

I also noticed that the \Spatie\LaravelData\Support\Caching\DataClassFinder:36 class adds the path __DIR__.'/../../' to cache some files used in this package (not sure which ones), but the reflection discovery will always search for classes names like:

"Class "Vendor\spatie\laravel-data\src\Support\Caching/../..\Resource" does not exist in the \Spatie\StructureDiscoverer\StructureParsers\ReflectionStructureParser::execute

    'structure_caching' => [
        'enabled' => true,
        'directories' => [app_path('Data'), base_path('vendor/acme/package/src/Data')],
        'cache' => [
            'store' => env('CACHE_STORE', env('CACHE_DRIVER', 'file')),
            'prefix' => 'laravel-data',
            'duration' => null,
        ],
        'reflection_discovery' => [
            'enabled' => true,
            'base_path' => base_path(),
            'root_namespace' => null,
        ],
    ],
