Add NodaTime example

[runerys]

The issue https://github.com/ch-robinson/dotnet-avro/issues/222 requests a demonstration on how to enable NodaTime support. This PR constributes an example for schema generation, serialization and deserialization.

Note that

• The schema generation considers the TemporalBehavior parameter and delegates to string or timestamp behavior.
• The value is serialized in the same behavior as a DateTimeOffset

This PR is setup as a draft for now, since:

• The test suite I have "on my computer/in my own solution" should be reorganized to fit in the example
• The program in the example should be run - I did a best effort for now.

This ran successfully for me on the Docker Compose stack we have in the examples directory 👍

Ah, brilliant! 👌

I got up and running, but somehow the consumer don't get any assignments through consumer.Subscribe().

• Topics are created
• The schema is generated fine
• Publishing works fine
• The broker logs seem fine:

• I tried to increase the assignment timeout (in case of general slowness), but with no luck.

However, direct assignment worked fine: consumer.Assign(new TopicPartition(Topic, 0)); So, I also got it running (quite) successfully.

Huh, yeah, I recreated everything and got the same problem. Everything should still work if we remove the check and set auto.offset.reset to earliest; going with that for the other examples: https://github.com/ch-robinson/dotnet-avro/commit/5c95d0a8702e4bd140ee63107005888631fc8038

Thanks! I rebased my branch and updated the setting. Works now.
