Edm4hep format as default when both edm4hep and lcio enabled

BEGINRELEASENOTES

• ddsim: Set edm4hep the default output format in case DD4hep is compiled with both DDD4HEP_USE_LCIO DD4HEP_USE_EDM4HEP ON
• ddsim: Change the name of the default output file from dummyOutput to ddsimOutput

Fine for me. Just want someone from ILD to OK as well.

Will this actually yield EDM4hep files and not the DD4hep format without the edm4hep.root suffix?

@gaede anything speaking against this? I think all of the worklows, tutorials, etc. get an LCIO output in any case, because we specify an output file name with .slcio in any case.

This PR does not change the behavior in case both the lcio and edm4hep flags are OFF (the dd4hep format is the default for rootfiles). If edm4hep is ON, rootfiles will be edm4hep (without the need of edm4hep.root in the name), but this was introduced in #1144.

If edm4hep is ON, rootfiles will be edm4hep

Thanks for the clarification. I have either missed that entirely or forgotten again in the meatime.

All good from my side then.
