Biome generation, Fog feature Updates and performance improvements

Updated Generator for enhanced biome generation, Fog feature Improvements and performance improvements

• Added support for multiple biomes: Modified the code to support multiple biomes in the header of the material files. You can now specify multiple biomes separated by commas.

• Updated Generator: Previously, the biome generation was done once per chunk, but it has been updated to check the biome for every block generated in the grid. This change ensures more accurate biome-specific generation and avoids issues where biomes don't extend all the way underground.
• Generator optimizations: Optimized to improve performance. Changes include storing constant values in local variables, minimizing block data modifications inside the loop, and reducing exception handling to enhance efficiency.
• Updates to Fog feature: Improved user experience by changing how the resource pack is installed. Previously, the resource pack was installed every time a player joined the server while the plugin was enabled. Now, the resource pack is only asked to be installed when the fogon command is used. This change provides a better experience for users who do not use the fog feature but were previously asked to install the resource pack every time they joined.

These changes allow for more precise biome-based block generation and improve the overall performance of the plugin. The updates ensure that the generated biomes are accurately represented throughout the world, overcoming limitations of the previous chunk-based approach.
