Updated Nuget Packages

Azos 1.5.4 -> 1.5.18
fastJson 2.3.5.2 -> 2.4.01
MessagePack 2.2.60 -> 2.2.85
protobuf-net 3.0.52 -> 3.0.73
ServiceStack.Text 5.9.2 -> 5.10.4
SpanJson 3.0.1 -> 3.1.0  this is no longer compatible to .NET Core 3.0 so I had to remove that as target framework which is only for historical reasons relevant. .NET Core 3.1 is still supported.
