Use pyproject.toml + uv_build

This replaces setup.py by a modern pyproject.toml using uv_build
backend.

Dependencies are being also managed by uv, so to install dependencies
and run the project one can execute:

```
uv sync
uv run pytest # optional
python -m avp
```

To build the both source and binary (wheel) distribution package run:
```
uv build
```

Uv can be installed with `pip install uv`.

The directory structure has been changed to reflect best practices.
- src/* -> src/avp/
- src/tests -> ../tests
