Fixes llm args + remove default NL assertions checks (#23)

* update README, update type in fig, add num tasks cli

* Made pip install -e the default. For non editable install, added option to set a TAU_DATA_DIR to point to the data. Added a fall back to local source if this is not set. Added tau2 check-data cli for people to check data install
fixed num-tasks flag. Fix display of tasks name in cli.

* Fix CLI parser for dict args

There is no way for `dict` to parse a CLI string into a dictionary, so `type=dict` is simply non-functional. This change fixes that by allowing users to pass JSON strings at the CLI to configure LLMs. 

I am using this to pass `api_key` and `api_base` for self-hosted LLMs on an OpenAI API-like endpoint.

* Fix brace escaping

* updated evaluator so that nl assertions are not run by default
