[Feature Request] Restructure ARC.ISA.JSON

[Freymaurer]

We should resolve the the following issues:

• Adapt coherent api naming.
• Update to Thoth.Json multitarget release
• Add ro-crate json support
• Unify ARCtrl.Template.Json api.
  • Fix someTemplate.ToJson() (has currently a missing template reference)
• Improve testing, which currently only tests against words and how often they exist.
• Move "Id" field of ISA-JSON to be used only in write-read scenarios, do not use this in datamodel

Due to the changes in api naming, resolving this issue will introduce breaking changes and should be planned out carefully!
