Added a .NET extension that provides a .NET wrapper so that .NET applications can access the NORM C API. It is modeled after the Java extension for NORM. Also, added integration tests to verify functionality and demonstrate usage. Added GitHub actions to run tests and publish the .NET extension to GitHub Packages. Included Dev Container to simplify the process of setting up a development environment. This closes #84.

Yes - the NormDataEnqueue() call pass the pointer to the application memory block and the application is responsible for keeping it intact and unmodified while the NORM sender has access to it. This is sort of an anachronism from the early days of our reliable multicast effort where we were focused on transfer of "bulky" content and when passinng very large objects in memory and NORM keep a potentially large cache of objects to provide repair/retransmissions for, it wasn't prudent for NORM to keep an internal copy of something the application was maintaining anyway. For smaller data object like messages, it is practical for NORM to maintain its own copy of the data and I have thought about allowing for that. In fact, the API may have a way to pass deallocation control down to NORM (if not, an option that could be added with appropriate use of accompanying NormAlloc() and NormDealloc() calls).

BTW - also posting here that I have been tracking this pull request loosely. Since there is some additional engagement on this and I've been busy, I haven't yet dived into closely review this request. If you both thinks it's ready for that, I will do that ASAP. Thanks for your contribution!

Having NORM copy on enqueue and deallocate when needed would certainly simplify things for the .NET code. Otherwise we're left with pinning or doing the exact same thing in C#. The performance impact of pinning seems difficult to estimate without measuring a real use case. But it negatively affects GC performance due to fragmentation and it would increase with the size of the transmit cache.

@bebopagogo Thanks for checking on the pull request and for clarifying NormDataEnqueue(). I am currently working on a feature branch to address the NormDataEnqueue() comments. The rest could use further review if time is available.

I think the initial code was better, just avoid LINQ and use the string constructor that takes the length of the buffer.
But that doesn't seem to be needed, see https://learn.microsoft.com/en-us/dotnet/fundamentals/code-analysis/quality-rules/ca1838#how-to-fix-violations. The stackalloc and PtrToStringAnsi variant should work fine.
