Add FY3-E MWSFY3E obtype

[david-rundle]

Add MWSFY3E obtype which is an almost straight copy of MWSFY3 with a few more channels (but it's still store in the MWTS MetDB type)

Thanks for adding this. I realise it's very similar to an existing case, but perhaps consider adding another Cx Writer ctest in order to ensure it is covered.

Looks good to me.

CI failing the same way as mo-bundle workflow running in my environment.

Thanks Chris - I've added a test. Hopefully correctly. But I notice that it's failing.

I haven't added anything to ioda which I notice is used here. Do I need to?

At the very least I forgot to actually run the python script to generate the unit test python which I have now done and added.

I see that ioda is a dependency but I don't have a PR to implement a test there yet. I'm in the process of adding it now.

Thanks for making the changes and adding the new test. I'll merge once the CI has completed.
