Enumerating the result of `BinaryLog.ReadRecords` twice crashes with `EndOfStreamException`

[jjonescz]

Steps to reproduce:

dotnet new console
dotnet build -bl # to create sample binlog
dotnet add package MSBuild.StructuredLogger --version 2.2.472

Replace Program.cs with:

using Microsoft.Build.Logging.StructuredLogger;

var records = BinaryLog.ReadRecords("msbuild.binlog");
records.ToList(); // ok
records.ToList(); // crashes

dotnet run

Observed output:

Unhandled exception. System.IO.EndOfStreamException: Unable to read beyond the end of the stream.

I'd say this is by design
