Add Compression Codecs for sub-entry

[Gsantomaggio]

By default client Support None and GZIP.
We need to provide the examples for:

Snappy = 2,
Lz4 = 3,
Zstd = 4,

as external codec to be compatible with:

• Golang Client
• Java Client

Hi!

I looked at an example, but there was a question. Dependencies for new codecs (wrappers over calls) should be included in the current project or go independently - a separate project including the main one or its part with interfaces? As far as I understand the rabbitmq-dotnet-client project follows the principle of the minimum number of dependencies

We don't want to add external dependencies. So the idea is to write the example, then it is up to the user to decide to add the dependency.

So you write your codec then add it with:

 StreamCompressionCodecs.RegisterCodec<StreamXXXCodec>(CompressionType.XXX);

That is, no need to integrate the codec into the library, but only to prepare examples. Need something like a documentation page (section in README.md)?

yes, maybe create a directory examples and put the code with the documentation.
