### Description
Currently, only one service can listen to libretime schedule change
events. This change allows for as many services as desired to listen for
schedule change events.
**This is a new feature**:
Yes
**I have updated the documentation to reflect these changes**:
No, as this seems like the obvious default
### Testing Notes
**What I did:**
I created 2 playout blocks, connected them both to the fanout queue and
saw that they could all connect and receive schedule change events at
the same time.
**How you can replicate my testing:**
