Tokio Version #44
Description
The tokio version is being explicitly locked at v1.22.
This is a problem with projects building with solana dependencies, that are locked at v1.14 of tokio.
We forked this repo and specified the tokio dependencies as v1 (not specifying a particular minor version). This fork successfully builds with solana dependencies. Which likely suggests that specifying v1.22 tokio here is unnecessarily strict.
Let's not specify the minor version of tokio here?
