IlcDisableReflection = Connection Error

[JackHarckness]

When compiling with MSBuild attribute <IlcDisableReflection>true</IlcDisableReflection>, RtspClient cannot connect to a stream. Otherwise it works great. I'm attaching a relevant portion of the stack trace but you know, it is very much crippled since IlcDisableReflection is true.

RtspClientSharp's version: 1.3.3

To Reproduce If you want a repro, create a console application, add <IlcDisableReflection>true</IlcDisableReflection> to your .csproj file, make an async call to RtspClientSharp.ConnectAsync. Compile it then to native code (<PublishAot>true</PublishAot> and dotnet publish on .NET 8.0+ will do the trick) and run. Otherwise you won't be able to see this error.

IlcDisableReflection is not supported and it can cause many components not working as expected.

[JackHarckness]

@hez2010 why do you think the reflection use is required within this library? Note that type checks like

if (e is RawH264IFrame intraFrame)
{
    //...
}

are still allowed in reflection-free mode. I would suggest a minor research and refactoring that will find and remove any reflection use. This can also lead to a minor performance increase.
