Fixed

• Before the Consumer and Reader would throw an ArgumentOutOfRangeException if they encountered a compressed message. Now they will throw a CompressionException if the compression type is not supported
• DotPulsarEventSource (performance counters) was only enabled for .NET Standard 2.1. Now it's enabled for all target frameworks except .NET Standard 2.0
