runtests should not print unnecessary text to command window and test log

Fixes #85

Add o1, remove the deprecated 3.5-0613 models.
Change examples from outdated 3.5-turbo models to newer ones (picked at random).

`topenAIChat/canUseModel` needed a change because the o1 models error with `MaxNumTokens=1`, as they need a few tokens to get the multiple stages started.

* Switch from Mistral to Mistral NeMo

Switch from Mistral to Mistral NeMo as the default model for tests and
(tested) examples, to prepare for supporting function calls in `ollamaChat`.

* Extract structured output tests

* Activate structured output for ollamaChat

* Improve error message when trying to use structured output with Ollama < 0.5.0

* extract tool call tests

* tool support for Ollama

* Adapt messageHistory to support Ollama specifics

* response streamer should capture tool calls outside OpenAI's format

* add Ollama function calling example to texampleTests

* Minimal documentation updates

* Split llms:assistantMustHaveTextNameAndArguments in two

To make the error messages simpler

Changed phi-3 to mistral, and llava to moondream.
