Added support for celluloid 0.18
Changelog
- The server and the client supporto also a log_level option to set the logging level
- When a client publishes to a channel where there are no subscribers the server will save those messages in the registry and will send them as soon as a client registers to that channel, afterwards those messages are deleted.
- Currently those messages are saved in memory.
Known Issues:
Does not work on Ruby 3.0.0 due to some errors with celluloid/io . Need to investigate that further
