resources generate images support

Is your feature request related to a problem? Please describe.

When adding a new image resource to your project, it would be handy to be able to add one without going through https://images.nativescript.rocks/ or manually creating your own and placing them in the right folders.

Describe the solution you'd like

An extension of the resources generate command could be used that would act almost identically to the generate icons command, however it would use the original file name instead of "icon" when creating the different image sizes.

Describe alternatives you've considered

Making the generate icons command take another (optional) argument which allows an output name to be specified would also solve this issue

Anything else?

Commencez par localiser la commande resources generate et son implémentation existante pour générer des icônes. Étendez la commande afin de générer les tailles d’image en utilisant le nom de fichier d’origine, ou prenez en charge un nom de sortie facultatif ; le travail est terminé lorsqu’une nouvelle ressource d’image peut être générée sans outils externes ni placement manuel dans un dossier.
