Handling a message in SObjectizer-5 by its base class?

[Yauheni Akhotnikau]

Hi!

It's a question that hasn't a possitive answer for a long time, but...

I've implemented a first working draft  and make a brief description with some open questions here: https://github.com/Stiffstream/sobjectizer/discussions/85

It's hard to say when the next version of so5extra will be released. I want to and one or two small features, so it takes some time, and I have to find that time first, it's not so easy ;)

I would appreciate any feedback on the described feature.
