Added support for DALL-E 3 and prompt verification

Extension has been updated to add the following features:

• You can now select DALLE-3 for Image generations.
• New command ‘Verify Prompt’ - you can now verify the prompt is safe before attempting to generate the image (0 cost)

How to update:

1. Back up any custom buttons or commands in the premade AI Image Generator deck in SAMMI, e.g. the INIT button.
2. Download the updated .sef file.
3. Install the extension. When SAMMI asks you to replace it, press yes. When SAMMI asks you to replace the deck, press yes.
4. Replace the new INIT button with the one you backed up, or simply fill it out with your credentials again.
5. You’re back in business!
