What's Changed

• fix: removes unnecessary fmt::Debug bounds on HierarchicalLayer, which makes it possible to compose HierarchicalLayer with other HierarchicalLayers (#​45).
• fix: check whether another HierarchicalLayer has already placed Data in the extensions; skipping if it's already present. This prevents the panic reported in tokio-rs/tracing#2112.

Thanks to @​conradludgate and @​joxcat for reporting this these issues!
