+/// 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!`)
