Async-std v0.99.10 released!

This week is a pretty big release; with over 70 new methods and types, improved documentation, and lots of smaller tweaks to continue improving the user experience. Big additions this week are: the path submodule is now complete, we now have stream::interval, and we've stabilized some of our futures concurrency macros.

Next week is probably going to be a bit quieter, as some of the team will be taking vacation. But we might still squeeze out a new release. We're very excited for the work we've done in the past week, and hope you all enjoy the new release!
