Support for D04B/MSCONS

Great project! I need support for MSCONS Messages.

I am happy to contribute. Could you point me to the entrypoints?

Thanks, so the underlying implementation come from https://github.com/apimeister/edifact-types - so all the edifact types go in there. The biggest obstacle so far is getting test data. So if you have some sample EDIs that you can share with the repo that would be great, the code then is rather straight forward, copy from the existing stuff until the test case is successful.
