Omni's Custom Items 1.0.31

- Renames the visible mod title to Omni's Custom Items.
- Adds the Iridescent Ball custom Poke Ball.
- Gives the Iridescent Ball x1 catch rate at night, x4 during the day, and x8 during daytime rain.
- Adds a 1% post-capture chance for the Iridescent Ball to turn the caught Pokemon shiny.
- Applies the catch multiplier through the ball's own Cobblemon CatchRateModifier.
- Uses iridescent_ball.geo.bbmodel as the source for the 3D thrown/capture ball model.
- Uses Iridescentball.png as the source for the inventory icon.
- Uses Iridescent_ball.png as the source for the 64x32 3D model texture sheet.
- Bakes the custom per-face overlay UVs into the runtime texture so Cobblemon can load the model with array-style UVs.
- Includes a source manifest at assets/pokeisles_foods/source_models/iridescent_ball_source_manifest.json.
- Preserves the existing Poke Isles food items and mechanics.
