Description
I'd like to store a class instance for reporting events to some open connection that was opened before tracing commenced. As the trace instance is already stored inside UserContext, it would be nice to have an additional field within krabs::trace_context (e.g. just a PVOID) which would be accessible from all event callbacks.

Research direction
Start by locating krabs::trace_context and UserContext, then trace how trace context is passed to event callbacks. Define how a user-provided context pointer would be stored and exposed across callbacks, and verify that callbacks can access the same value for the lifetime of the trace.
