/// Opens a scope. Two variants:
///  - profiling::scope!(name: &str) - Opens a scope with the given name
///  - profiling::scope!(name: &str, data: &str) - Opens a scope with the given name and an extra
///    datafield. Details of this depend on the API, but it should be a &str. If the extra data is
///    named, it will be named "tag". Some APIs support adding more data (for example, `optic::tag!`)

/// ```
/// profiling::scope!("outer");
/// for _ in 0..10 {
///     profiling::scope!("inner", format!("iteration {}").as_str());
/// }
