Re: [web-nfc] Improve description of NFCWatchOptions.recordType attribute

I don't see the point in having it nullable either. You can make it absent or add undefined instead.

Actually if you mark something as undefined, it will still be iterable.

```
a = { hest: null, nonhest: undefined }

for (var entry in a) { console.log(entry) }
VM214:1 hest
VM214:1 nonhest
```
