Bump version to 2.0.0-beta001

- Switches TaskResult Library from TaskBuilder to Ply. Credits [Nino FLoris](https://github.com/NinoFloris) - (#97)
- This change replaces [TaskBuilder](https://github.com/rspeele/TaskBuilder.fs) with [Ply](https://github.com/crowded/ply).  Ply has better performance characteristics and more in line with how C# handles Task execution.  To convert from TaskBuilder to Ply, replace the namespace of `FSharp.Control.Tasks.V2.ContextInsensitive` with `FSharp.Control.Tasks.NonAffine`.
- This also removes the TargetFramework net461 as a build target. Current netstandard2.0 supports net472 fully according to [this chart](https://docs.microsoft.com/en-us/dotnet/standard/net-standard#net-implementation-support). It's recommended to upgrade your application to net472 if possible. If not, older versions of this library, such as 1.4.3, aren't going anywhere and can still be consumed from older TargetFrameworks.
