Script for the creation of metadata and the randomization of images of MekaVerse

1. Create a folder : output
2. Retrieve the 8,888 images (48gb) without renaming them, and put them in the output folder.
3. Delete from output folder the image of Meka #5227 that was added after : camogreen_darkgrey_lightgreen_camogreen_lightgreen_lightgreen_C_4C_4C_6C_1C_3C_2C_0_0_0_0_0_0_2033.png.
4. Add in the output folder the placeholder by naming it 1080_placeholder.png
5. Add in the output folder a file named Thumbs.db that had nothing to do with it.
6. The random was launched before the revelation of Legendary Mekas, so you must remove legendary pictures and put 4 files in output folder : Legendary_Meka_Tickets_1.png, Legendary_Meka_Tickets_2.png, Legendary_Meka_Tickets_3.png, Legendary_Meka_Tickets_4.png
7. Run the python script python set_metadata.py

The generation.json file show you exactly the same result as on OpenSea (with missing metadata for the Meka #5227)
