tracing-futures: Release version with pin-project-lite

[theduke]

I'm currently on a mission to reduce dependency counts in a project, and pin-project is one offender.
Most of the ecosystem has switched over to pin-project-lite where possible, so it ends up in every dependency chain.

pin-project was already replaced with pin-project-lite in tracing-futures quite a while ago in #1185 , but there never was a new release that includes this change.

It would be great to see new release.

Is there any discernible benefit to using pin-project-lite instead of pin-project? Don't quote me on this, but I think some of pin-projects unique features are used in tracing Dont think so, actually.
