[slog_scope] scope() and await

[Geobert]

Hi,

I'd like to add key:value to a logger and to do so, I'm calling slog_scope::scope where a pass a new logger with the needed key:values.
the issue is that the code in the function is async and the await are not accepted.

Is there a way to work around that?

If you're writting async code, I would consider using tracing ecosystem instead anyway.

Other than this, slog-scope would need a an async feature flag and a new set of functions that are async-enabled. PRs welcome, but probably easier to just use tracing and get other async goodies.
