Use the newly introduced namespace in the conversion

BEGINRELEASENOTES

• Use the EDM4hep2LCIOConv namespace (introduced in Introduce namespace for EDM4hep to LCIO conversion k4EDM4hep2LcioConv#27) in the EDM4hep to LCIO conversion tool.

ENDRELEASENOTES

Split this off of the bigger work of having unified maps for the converters.

Failing CI seems to be unrelated and should be fixed by #139

I am not sure if @jmcarcell has a preference on the order in which we merge this and key4hep/k4EDM4hep2LcioConv#27. In principle this one could go in now, and I checked locally that things still compile once the other one is merged as well. Should we leave one nightly between the two, or should we rather merge them in one go?

This is not going to hurt anything, so let's put it in now.

Let's merge and blame you if it doesn't work :D
