/*
Monitor - represents a Redis MONITOR command, allowing the user to capture
and process all commands sent to a Redis server. This mimics the behavior of
MONITOR in the redis-cli.

Notes:
- Using MONITOR blocks the connection to the server for itself. It needs a dedicated connection
- The user should create a channel of type string
- This runs concurrently in the background. Trigger via the Start and Stop functions
See further: Redis MONITOR command: https://redis.io/commands/monitor

Solutions

1. Pass a non-nil ModuleLoadexConfig to ModuleLoadex
2. Construct the config struct (even if fields are defaults) before calling

When it happens
