Combine zn.deps and zn.nodes to zntrack.deps

[PythonFZ]

This uses the name key in the zntrack.json to identify a zn.nodes as follows

"instance": {
  "_type": "zntrack.Node",
  "value": {
    "module": "ipsuite.nodes",
    "cls": "SmilesToAtoms",
    "name": "parent:attr:<idx|key>",
    "remote": null,
     "rev": null
  }
},

• remove logging statements
• fix all tests
• tests for 3f7d00f !
• use from typing_extensions import deprecated for the zn and dvc modules (Deprecate zntrack.zn.<field> and zntrack.dvc.<field> #722)
• check that it works with groups (group names are currently applied after the name of the zn.nodes is set)
• check that it works with _name_ = "CustomNodeName"
• zn.nodes with node.attr tests
