Update HydroID with Seed

Description

Given a workspace, update the HYDROID, and Related IDs [e.g., FeatureID, StreamID, DrainID, NextdownID, RiverID etc] with a specified Seed value, e.g., Seed=10000000. The layer and the fields are specified by an configuration json file (optional). The content of json file looks like this:

{
  "layers": [
    {
      "layer":"fpzoneriver",
      "fields":[
        "StreamID"
        ]
    },
    {
      "layer":"fpriver",
      "fields":[
        "HydroID",
        "DrainID",
        "NextDownID",
        "SplitID",
        "GRIDID"
        ]
    },
    {
      "layer":"fpcatchment",
      "fields":[
        "HydroID",
        "NextDownID",
        "StreamID",
        "GRIDID"
        ]
    },      
    {
      "layer":"pf_ModelStream",
      "fields":[
        "StreamID",
        "RiverID",
        "GridID"
        ]
    },      
    {
      "layer":"TSXRef",
      "fields":[
        "FeatureID",
        "KeyTo"
        ]
    }   
  ]
}

If the optional config json file is not provided, a default json_string is provided in the code.
