Json schemas for VSCode YAML Support

The `xshell` crate provides a more convenient way to build and run a `Command`, which is more similar to traditional bash scripts. Using this crate, we can simplify our `run.rs` script while still being platform-independent and not requiring any external dependencies. We can also still run the examples using `cargo run --example`.

Convert rust example to node

Simplify parsing of `AMENT_PREFIX_PATH`

Minimal conversion from previous operator api to node api.

Ref #474

Fix CI by ficing widestring proc_macro, fixing clippy, adding CI flag

fix CI with minor changes

This PR simplify how ROS2 messages are parsed using dora.

It will parse all messages included in the `AMENT_PREFIX_PATH` folder
that has a path in the following format: `<package>/msg/<message>.msg`.

Similarly for services it will be parsed as: `<package>/srv/<service>.srv`.

It does not requires `.idl` anymore nor does it needs to be in the `ament_index`.

Update `ros2-client` to latest version

Update to use https://github.com/jhelovuo/RustDDS/pull/334 .

This commit makes it possible to specify the conda env that we want to use in
a specific operator.

```yaml
  - id: robot
    operator:
      python:
        source: ../operators/robot.py
        conda_env: robomaster
```

This will call:
```bash
conda run -n robomaster python -c "import dora; dora.start_runtime()"
```

Enable ROS2 service calls from C++ nodes

Add initial support for calling ROS2 services from Rust nodes

Call the `add_two_ints` service and check the result. This requires that the following command is executed in a separate terminal before:

`ros2 run examples_rclcpp_minimal_service service_main`

This commit makes it possible to:
- Concurrently write records of data
- Use Apache Parquet Compression to reduce storage size to avoid slow transfer speed.

Send runs artefacts into a dedicated `out` folder

Add option to send `stdout` as node/operator output

Use the subscriber type for downcasting to ensure that the correct type is used. Also, store an unique ID per subscriber to differentiate subscriptions of same type after merging.
