/api/results/upload : Handler for receiving a CSV results file previously returned by /api/results.
POST method receives the data file and begins the process of parsing the results.
The multipart-encoded parameters are:

results

Results file to upload.

csvFieldDelimiter

Optional character for delimiting the CSV field. If not specified, the delimiter will be inferred from the first line of the file.

targetColumn

Optional column name that identifies each match. The default is MatchId

Output: a JSON-encoded response object of the usual structure for which the model is an object with a threadId attribute, which is the ID of the server task to monitor file parsing progress. e.g.
```
{
    "title":"upload",
    "version" : "20250711.1119",
    "code" : 0,
    "errors" : [],
    "messages" : [],
    "model" : {
        "threadId" : "80"
    }
 }
```
The task, when finished, will output a URL for accessing the matches of the search.
