Hello, Andrew @areusch

Implementing the **Project API** , am encountering a couple of issues:

1. The `generate_project` script takes one tar ball with a model, multiple models do not seem to be supported. I would propose to add a function `add_model(module_library_format_tar)` that will add a given model to the project. Or any other solution you may prefer, so that a project could include multiple models ?
2. We have the stm32 runtime API code that is not included with the `standalone_crt` distribution. How do you propose the project accesses this runtime code ?
3. I can test the `ProjectAPIHandler` methods (from the `microtvm_api_server.py`) directly from a small script, verifying the functionality for `generate_project`, `build`, and `flash`. However, I have not found the `project_api` in the main branch, or is it ? How do you propose I continue ?
