* Refactor `messageHistory` to be agnostic of the image encoding.
* Add backend encoding of images to `openAIChat`, `azureChat`, and `ollamaChat`.
* Add image test points to the test files.

Open question: Can we reliably detect which Ollama models support vision?

Preinstall bakllava, to have a vision model

moondream is a much smaller vision model and perfectly suitable for the tests we want to run.

Replace bakllava by moondream

Create CODEOWNERS

To decouple `texampleTests.m` from availability and speed of external servers,
record calls to `llms.internal.sendRequest` (on dev machine) and replay
(during most test runs, including CI). See tests/recording/README.md for
instructions.

The streaming interface sometimes responds with something like `json.choices = {"index":0,"delta":{},"logprobs":[],"finish_reason":"length"}`. Stop blindly assuming `json.choices.delta.content` exists.

Avoid bogus access to `json.choices.delta.content`

Trace/replay `llms.internal.sendRequest`

The moondream model is unreliable in reporting peppers or even reporting anything at all, notice the empty responses in several of these calls:

```
>> disp(generate(chat,messages))

 The image features a bunch of fruits and vegetables, including several bell peppers and chilies in various colors such as red, green, yellow, purple, and white. There is also an onion and some garlic on the table along with other food items that could be related to a meal or ingredient preparation.
>> disp(generate(chat,messages))

 The image displays a group of fresh vegetables on top of purple fabric. Among the vegetables are several peppers and garlic, some lying flat while others stand tall or in various positions.
>> disp(generate(chat,messages))
urn of different colored vegetables such as peppers and onions are placed on a table.
>> disp(generate(chat,messages))

 The image shows an assortment of various colorful vegetables, primarily focused on the peppers. There is a wide range of vegetables displayed in different shapes and sizes, creating a visually appealing arrangement that highlights their unique characteristics.
>> disp(generate(chat,messages))
>> disp(generate(chat,messages))

 The image displays a table with an arrangement of colorful, whole vegetables such as peppers and onions. These ingredients are spread across the table, showcasing a variety of colors including reds, oranges, greens, yellows, and purples. There is also an onion among these vegetables, further adding to their vibrant appearance. Overall, the scene captures a visually appealing display of fresh produce.

Since we are not interested in testing the model, but we do want to run an end-to-end test to ensure that we pass images in the data format required by Ollama, generate multiple responses and make sure that at least one of them mentions `"pepper"` or `"vegetable"`.

Allow "pepper" or "vegetable"
