[guide] Datamap

[Brilator]

Swate / ARCitect now allows to "Add Datamap".
This concept has not been introduced to standard users at all.

I would suggest to

• add an article about data map
  • what is it?
  • why do we need it?
  • how does it relate to other ISA / ARC / CWL concepts and entities
  • add example table
• add a guide on creating a data map

I know that it's not all final (see nfdi4plants/ARC-specification#113), but if we offer it to users, we should at least link to a little place holder ("under construction") article.

To be 100% honest with you, i just followed specification, as @HLWeil is on vacation 😅

It is meant to further describe data files.

Ah great, I missed that in addition to the ARC specification there is another one for ISA-XLSX

Maybe use motivation from nfdi4plants/ARC-specification#104 as a first starting point of the guide page?
