[new release] trace (2 packages) (0.4)

CHANGES:

- add `?data` to `counter_int` and `counter_float`
- add `float` to user data
- add `add_data_to_current_span` and `add_data_to_manual_span`
- make `explicit_span.meta` mutable
- trace-tef: write to `trace.json` if env variable `TRACE` is either 1 or true
- trace-tef: emit function name, if provided, as a metadata key/value pair
- re-export trace.core in trace

- perf: in trace-tef, use broadcast instead of signal in the job queue
