Semi-tolerant YAML concrete syntax tree parser.

## Usage

```rust
match yaml_parser::parse(&code) {
    Ok(tree) => println!("{tree:#?}"),
    Err(err) => eprintln!("{err}"),
};
```

It produces rowan tree if succeeded.
For consuming the tree, see [rowan's docs](https://docs.rs/rowan).

If you need to build AST from CST, use `ast` module:

```rust
let root = yaml_parser::ast::Root::cast(tree).unwrap();
dbg!(root);
```
