Messagepack-csharp: Unity Package Manager Support

[HardcodedNumber]

It would be nice to see Package Manager support https://docs.unity3d.com/Manual/upm-ui.html

This would allow me to use the same version for my server and client, as I build my server from another solution outside of Unity.

UPM is not same as NuGet(server package manager) so can not share.
But UPM support is good for better supporting to Unity.

Hello. I wanted to ask if it's possible now to install message pack via UPM. I haven't found any mention of it in the Unity installation section of readme and the latest related issue #1000 is still open. What's the current status of the feature?
