reporting: unify command line interface for reporting analysis modules

[leondz]

The CLI scripts in garak.analyze don't have consistent patterns for usage. They should be aligned so that:

• they all use argparse or typer to get parameters
• they all have a help / description section showing e.g. garak version (check out garak.cli for a pattern)
• command line parameter names are consistent across all the scripts
• each command line parameter has a short and long name (e.g. -o and --output)
• they don't execute when imported, just when invoked directly - see garak.analyze.report_digest for an example

The cli-accessible scripts in this package are:

• aggregate_reports
• analyze_log
• count_tokens
• get_tree
• misp
• perf_stats
• qual_review
• report_avid
