  Reposition README's opening sentence to highlight LLM data toolkit

  Why:

  CURRENT

  Dolma is two things:
  
  1. **Dolma Dataset**: an open dataset of 3 trillion tokens from a diverse mix of web content, academic publications, code, books, and encyclopedic materials.
  2. **Dolma Toolkit**: a high-performance toolkit for curating datasets for language modeling -- this repo contains the source code for the Dolma Toolkit.

  ## Why Dolma for LLM Data?
  While general-purpose data processing frameworks like Apache Spark, Dask, or Hugging Face Datasets Library can handle large data, Dolma is purpose-built and optimized for the unique challenges of curating massive text datasets specifically for large language model pre-training. It offers specialized taggers, fast deduplication, and a workflow tailored to the LLM data lifecycle, providing higher performance and relevance for this specific task compared to adapting general tools.
