tef: carry additional data for manual spans in the explicit_span's map 
the span opening has been emitted already, so we'll emit the metadata at
exit time. We don't need side storage since we already have a hmap.

trace-tef: emit function name, if provided, as a metadata key/value pair 
the key is "function". It is visible when selecting the span, typically.

a09a4fc69a refactor collector API as well. 
After long discussions with @ELLIOTTCABLE, the collector should only
provide a `with_`-like function for regular spans. This allows
each concurrency library to use its native mechanism for local storage,
which is almost always based on such a scope function.

b44e2f2923 Add explicit spans, for async tracing. 
These spans require the user to pass the surrounding span, if any, when
entering a new span. They use the information inside (which is collector
specific) to track what asynchronous task is currently being executed.

Wrappers around `trace`, specific to an async library (e.g. Eio, lwt,
Async, etc.) can then smooth this over by providing a `with_async_span`
construct that uses some implicit contextual storage to carry the
`surrounding` scope around.

f8cd53ec89 chore: depend on core in trace-tef 
This changes trace-tef to depend on trace-core instead of trace, to
avoid clashing with the toplevel's Trace module when starting utop.
