Crate tracing_helpers

Helpers for using the tracing crate more effectively.

In particular, this includes extension traits to make it easier to pass errors to tracing events. The events can take a dyn Error, but getting a dyn Error from an arbitrary error type requires casting.

Hopefully this crate will be short lived as tracing ergonomics continue to improve.
