My immediate question from this is "is there an escape mechanism to allow for "." in a field name?". I checked and the answer's no. That's fine but it might be worth a note.

I'll do even better than that and instead 🎣 for real support:

/// ```
/// # use parquet_variant::{VariantPath, VariantPathElement};
/// /// You can also convert strings directly into paths using dot notation
/// let path = VariantPath::from("foo.bar.baz");
/// let expected = VariantPath::from("foo").join("bar").join("baz");
/// assert_eq!(path, expected);
/// ```
///
/// # Example: Accessing Compound paths
/// ```
/// # use parquet_variant::{VariantPath, VariantPathElement};
