* Templates sometimes have BOS in them, remove duplicate
* tokenize chat format prompts before completion
This is to ensure that we don't duplicate any special tokens.
Hopefully I amended the existing formats correctly?
* updated comment
* corrected a few
* add some missing internals
* proper bos/eos detection
* just let tokenizer do the job
* typo--
* align test with new response
* changed to a warning
* move to another PR
* Use python warnings module

* fix: Refactor chat formatter and update interface for jinja templates
- Simplify the `llama2_template` in `llama_jinja_format.py` by removing unnecessary line breaks for readability without affecting functionality.
- Update `ChatFormatterInterface` constructor to accept a more generic `Optional[object]` type for the template parameter, enhancing flexibility.
- Introduce a `template` property to `ChatFormatterInterface` for standardized access to the template string.
- Replace `MetaSingleton` metaclass with `Singleton` for the `ChatFormatterFactory` to streamline the singleton implementation.
These changes enhance code readability, maintain usability, and ensure consistency in the chat formatter's design pattern usage.

* Do not set `grammar` to `None` for new `LlamaGrammar` objects
The `grammar` attribute is written by `init()`, but that method always
returns `None`, so `__init__()` would then discard the previously
written object.
* Add minimal test for grammar parsing
* Add low-level batching notebook
* fix: tokenization of special characters: (#850)
It should behave like llama.cpp, where most out of the box usages
treat special characters accordingly
* Update CHANGELOG
* Cleanup
* Fix runner label
* Update notebook
* Use llama_decode and batch api
* Support logits_all parameter

Define an init_llama function that starts llama with supplied settings instead of just doing it in the global context of app.py
This allows the test to be less brittle by not needing to mess with os.environ, then importing the app
