Subject: [PATCH 3/8] Updated parsing of VAU responses: * Read the content from
 the byte array, without converting it to string first which might cause
 unexpected changes to the result * Headers are now correctly added to both
 HttpResponseMessage and HttpContent

Added note to README regarding usage with record system

+Unter Verwendung der Klasse `VauHttpClientHandler` lassen sich Aufrufe des Aktensystems via `HttpClient` transparent ver- und entschlüsseln. Die Tests in der Datei [VauClientTest.cs](lib-vau-csharp-test/VauClientTest.cs)
