Prometheus.DiagnosticSourceAdapter missing in .NET Framework build

[hickford]

I'd like to use Prometheus.DiagnosticSourceAdapter but it's missing in the .NET Framework build

It appears to be compiled only on .NET https://github.com/prometheus-net/prometheus-net/blob/master/Prometheus/DiagnosticSourceAdapter.cs

What's the reason for this? It would be good to explain at https://github.com/prometheus-net/prometheus-net/blob/master/README.md#diagnosticsource-integration

Use case: my .NET Framework app has System.Diagnostics.Metrics . I'm using NuGet package https://www.nuget.org/packages/System.Diagnostics.DiagnosticSource/

The holds for the MeterAdapter: that would also work on .NET Framework by referencing the NuGet package Microsoft.Extensions.Diagnostics.
