feat(core): add CLI EventHandler

[mhordynski]

Feature description

A new CLIEventHandler would be responsible for logging all events from Ragbits in a human-readable way to the console. It is intended for use by engineers while developing or debugging their applications to enhance their observability into the system.

The handler should leverage rich library, utilizing colors, tables, and other formatting tools to ensure the output is as clean and readable as possible.

Motivation

Good feedback makes developing applications easier and more enjoyable.

Additional context

Ways to enable this handler:

• directly by passing it to ragbits.core.audit.set_trace_handlers
• from CLI by having global option --verbose / -v
• by having RAGBITS_VERBOSE=1 environment variable
