Figuring out how to use Tracing's logging layers for buttplug protocol log message output

[qdot]

Feature Description

In order to send out tracing messages as Buttplug log messages, we need to have a logger which we can add a layer to. Need to figure out how to either grab or create a new global logger, then what's needed to build a layer that will export messages to the output channel of the server.

[qdot]

Done. ButtplugLogHandler now just creates a layer object which can either be used in a registry or another subscriber.
