mod_muc_rtbl: also filter messages This was a bit tricky because we don't want to run the JIDs through SHA256 on each message. Took a while to come up with this simple plan of just caching the SHA256 of the JIDs on the occupants. This will leave some dirt in the occupants after unloading the module, but that should be ok; once they cycle the room, the hashes will be gone. This is direly needed, otherwise, there is a tight race between the moderation activities and the actors joining the room.

This module subscribes to a real-time blocklist using pubsub (XEP-0060). As
entries are added and removed from the blocklist, it immediately updates a
local service-wide ban list.

# Configuring

Load this module on your existing MUC component like so:

```lua
Component "channels.example.com" "muc"
modules_enabled = {
	-- other modules etc
	"muc_rtbl";
}
```

Then there are two options, which must be set under the component or in the
global section of your config:

```
muc_rtbl_jid = "rtbl.example"
muc_rtbl_node = "muc_bans_sha256"
```

# Compatibility

Should work with Prosody >= 0.11.x

# Developers

## Protocol

This version of mod_muc_rtbl assumes that the pubsub node contains one item
per blocked JID. The item id should be the SHA256 hash of the JID to block.
The payload is not currently used, but it is recommend to use a XEP-0377
report element as the payload.
