mod_vcard_muc: Add an alternative method of signaling avatar change When the avatar has been changed, a signal is sent that the room configuration has changed. Clients then do a disco#info query to find the SHA-1 of the new avatar. They can then fetch it as before, or not if they have it cached already. This is meant to be less disruptive than signaling via presence, which caused problems for some clients. If clients transition to the new method, the old one can eventually be removed. The namespace is made up while waiting for standardization. Otherwise it is very close to what's described in https://xmpp.org/extensions/inbox/muc-avatars.html

# Introduction

This module generates a badge for MUC rooms at a HTTP URL like
`https://conference.example.com:5281/muc_badge/room@conference.example.org`
containing the number of occupants.

# Configuration

  Option             Type     Default
  ------------------ -------- --------------------------
  `badge_count`      string   `"%d online"`
  `badge_template`   string   A SVG image (see source)

The template must be valid XML. If it contains `{label}` then this is
replaced by `badge_label`, similarly, `{count}` is substituted by
`badge_count` with `%d` changed to the number of occupants.

Details of the HTTP URL is determined by [standard Prosody HTTP server
configuration][doc:http].

# Example

```lua
Component "conference.example.com" "muc"
modules_enabled = {
    "muc_badge"
}
```
