/// Returns the path to an asset of the application.
///
/// On supported platforms this returns an asset bundled in the application. Supported platforms are:
/// - Any Linux/Unix when app is packaged as an AppImage,
/// - macOS (when app is packaged as a .app),
/// - iOS
///
/// In the case a platform/packaging method isn't supported this function still returns a path based
/// on executable location.
///
/// For macOS and iOS, localization is still supported by the app however assets could also be localized
/// in the app bundle as this function uses Apple APIs (CFBundleCopyResourceURL) to obtain the location
/// of resources.
///
/// Returns None if there is a system issue, ex: the system didn't return a proper path to the current
/// executing application. This should rarely occur.
