Remove Nito.AsyncEx dependency, add replacements
This change removes all uses of the Nito.AsyncEx NuGet package from the solution. This change was made to remove the use of this third-party dependency so that consumers don't need to get extra open-source approval when using PowerShell Editor Services. Removing this dependency required the creation of our own custom implementations of the classes we were using from Nito.AsyncEx. These new classes were written from scratch. Resolves #115
