readme: You need a custom version of the `tokenizers` library to use this tokenizer.
  
  To install this custom version you can:
  ```bash
  pip install transformers
  git clone https://github.com/huggingface/tokenizers.git
  cd tokenizers
  git checkout bigscience_fork
  cd bindings/python
  pip install setuptools_rust
  pip install -e .
  ```
  
  and then to load it, do:
  ```python
  from transformers import AutoTokenizer
  
  tokenizer = AutoTokenizer.from_pretrained("bigscience-catalogue-data-dev/byte-level-bpe-tokenizer-no-norm-250k-whitespace-and-eos-regex-alpha-v3-dedup-lines-articles")
  ```
