Efficient Data Loading
Adds a faster unified Parquet save/load path while keeping backward compatibility with CSV. The reason this wasn't done originally was so that people could use without pandas but this seems a pointless reason to inconvenience everyone...

Details

  • Unified Parquet format: store node and surface data in a single file for faster loading and easier model management.
  • Direct comparison test added (including a zipped model file).
  • Performance benchmarks in test
  • Made date parsing more comprehensive to accommodate this.
