mod_adhoc_dataforms_demo: Fix duplicate field prevention It's supposed to only include each type of form field once per form at most but it didn't note which fields it had added already. No idea what the probability was anyways, probably pretty low.

# Introduction

This module adds additional metadata to media shared in a MUC. This can help clients
make decisions and provide better UI and enhanced privacy, by knowing things like file
size without needing to make external network requests.

# Configuring

## Enabling

``` {.lua}
Component "rooms.example.net" "muc"
modules_enabled = {
    "muc_media_metadata";
}
```

## Settings

There are no configuration options for this module.

## Example stanzas

A normal message in a chatroom containing an image:

```
<message from="test@rooms.example.com/matthew" id="9f45a784-5e5b-4db5-a9b3-8ea1d7c1162d" type="groupchat">
  <body>https://matthewwild.co.uk/share.php/70334772-ff74-439b-8173-a71e40ca28db/mam-flow.png</body>
  <x xmlns="jabber:x:oob">

  </x>
</message>
```

The same stanza with this module loaded now contains additional metadata added by the server:

```
<message from="test@rooms.example.com/matthew" id="9f45a784-5e5b-4db5-a9b3-8ea1d7c1162d" type="groupchat">
