Allow for JSON string to be processed in the Sensor DataFilter

A clear and concise description of what the problem is. Ex. I'm always frustrated when [...]
When using gjson to evaluate the path of the DataFilter it returns a Result. You are using Result.Str here. With gjson you can return a JSON object by utilizing a Multipath. However, when utilizing this Multipath the Result.Type is JSON and thus the Result.Str returns an empty string and nothing is ever matched by the filter. You can however call Result.String() which correctly returns the string based on the Result.Type.

Describe the solution you'd like
A clear and concise description of what you want to happen.
What I'm trying to achieve is I have a webhook defined for an event and I want to filter the calls based on a value and depending on that value I may or may not want to filter if another value is something. For example:

{
  "body": {
    "action":"opened",
    "labels": [
      {"id":"1234", "name":"Webhook"}, 
      {"id":"5678", "name":"Approved"}
    ]
  }
}

I want the sensor to fire if my action is "opened" and it has a label of "Webhook" or if the action is "closed" and it has a label of "Webhook" and "Approved". Given the value of the DataFilter can be a regex I can use the gjson syntax to do something like:

[body.action,body.labels.#(name=="Webhook").name,body.labels.#(name=="Approved").name]

This produces a String like this:

["opened","Webhook","Approved"]

Then I could do a regex with something like:

(\bopened\b.*\bWebhook\b)|(\blabeled\b.*(\bWebhook\b.*\bApproved\b))

To filter the way I want. However, like I mentioned above the Result.Str is empty when the Result.Type is JSON and thus would need to code changed to call Result.String()

I tried I ton of different ways to filter based on what I want but can't come up with anything else.
