Setup uv package management for examples

[VigneshVSV]

We should be able to install all dependencies with a simple pyproject.toml and uv

Add all the dependencies found in all sub projects to the toml file.

Check if they can be installed using

uv venv
uv sync -- no-install-project 

Since we dont want to build the project, dont create a build backend.

To test, remove any auto-connect or device driver specific logic in init and see if the Thing is starting up.
