///
/// Use `Manifest::from(...)` to construst it.
///
/// It can be construsted from:
/// * Single or list of [`Feature`](crate::manifest::Feature) to compose a new manifest.
/// * Path to a manifest. (must be a [`PathBuf`](std::path::PathBuf) or [`&Path`](std::path::Path))
/// * Contents of a manifest as a [`String`].
///
/// ### Example:
/// ```
/// # use winscribe::manifest::{Manifest, Feature, DpiMode};
/// # use std::path::Path;
/// // From features:
/// Manifest::from([
///     Feature::DpiAware(DpiMode::PerMonitorV2),
///     Feature::ControlsV6,
/// ]);
/// // From path:
/// Manifest::from(Path::new("my_manifest.xml"));
