Merge #550: Pin tokio version to ~1.14

b04bb59 Pin tokio version to ~1.14 (Steve Myers)

Pull request description:

  ### Description

  The `tokio` project recently changed their MSRV to `1.49.0`. This PR will pin the `tokio` dependency version to `~1.14` which is prior to their MSRV increase.

  ### Notes to the reviewers

  The LDK team took this approach for their `tokio` dev-dependency, see lightningdevkit/rust-lightning#1315.

  As long as `tokio` backports bug fixes  to`1.14.x` releases this should be safe. If we need any new features we can revisit this decision.
