Add Option Groups to parser

[epi052]

I'd like to have groups of options visually ... grouped together. Maybe not exactly these groups, but something along these lines. Currently clap doesn't offer this functionality but will in version 3.0.

Once clap 3.0 is released, this ticket can be completed.

Filter Options:
    -S, --filter-size <SIZE>...             Filter out messages of a particular size (ex: -S 5120 -S 4927,1970)
    -C, --filter-status <STATUS_CODE>...    Filter out status codes (deny list) (ex: -C 200 -C 401)
...

 Include Options:
    -s, --status-codes <STATUS_CODE>...     Status Codes to include (allow list) (default: 200 204 301 302 307 308 401)
...

Scan Options:
...

Client Options:
