Feature Request: Start fuzzing from a specific word in the wordlist

When a scan is interrupted because of rate limiting (429), WAF blocking (403), or a network issue, users often know the last processed word from the console output. It would be useful to allow restarting the scan from that word instead of replaying the entire wordlist.

Proposed CLI:

ffuf -w wordlist.txt -u https://target/api/v2/users/FUZZ --start-from john

ffuf would skip all entries until it reaches the specified word, then continue normally

I'd be happy to work on implementing this feature if it aligns with the project's direction. Before starting, I'd like to get your feedback on the proposed approach and CLI design.
