Add processing:name to complement processing:version

[hrodmn]

processing:version describes the version of the primary processing software or chain, but there is no corresponding field for its name. processing:software can list multiple tools without identifying the primary one, while processing:lineage is free text.

I propose that we add an optional processing:name string identifying the primary software or processing chain. When both fields are present, processing:name and processing:version would describe the same software or chain.

Maybe name is not the right term but something to identify the thing that processing:version describes could be helpful.

👍🏼 From the processing:version description:

The version of the primary processing software or processing chain that produced the data.

This implies that there could be other processing softwares or chains, so a name field to specify which software or chain makes sense.
