Cannot update Scene -- parameter not modifiable

Probably related to #45 -- the `recycle` parameter is marked as `bool` without any `omit` directive. It works for creating the scene but not for updating it.

**Steps to reproduce the issue:**
1. Try to update a scene name
2. Error: parameter, recycle, is not modifiable

**Describe the results you received:**
I am implementing a terraform provider, this is the JSON:
`{"name":"Testing","recycle":false}`

`│ Error: ERROR 8 [/scenes/jeU0J-6kXNVvnnL/recycle]: "parameter, recycle, is not modifiable"`

**Describe the results you expected:**

**Hue Bridge Version**

```
"apiversion": "1.48.0",
"swversion": "1948086000",
```

**Can I help?**

I am learning go as I write this provider, if you provide me some pointers I can contribute towards the solution.

My naive solution would be adding a map to the "update" instead of using the struct so we have fine control over the elements -- but I think the solution from #45 would solve this in a better way.
