Feature Request - Introduce `coffee new` Command

## Description
We propose the addition of a new command: `coffee new`. This command will simplify the process of creating new plugins.

## Command syntax
```bash
coffee new --lang= --plugin
```

## Desired Outcome
The `coffee new` command is expected to generate a new directory containing a ready-to-use plugin template. This template will serve as a starting point for developers, offering a structured foundation for plugin development.
