Instruct tokenizer

The HuggingFace tokenizer included in this release should match our own. To compare: pip install mistral-common

Function calling and special tokens

This tokenizer includes more special tokens, related to function calling :

[TOOL_CALLS]
[AVAILABLE_TOOLS]
[/AVAILABLE_TOOLS]
[TOOL_RESULT]
[/TOOL_RESULTS]

If you want to use this model with function calling, please be sure to apply it similarly to what is done in our SentencePieceTokenizerV3.
