Consider adding crowdsec

[cheesestickstomatojuice]

Hi there,

I noticed the script you set up for fail2ban. While it's an effective tool for blocking intruders and managing IPs after multiple attempts, I wanted to highlight CrowdSec as a strong alternative. CrowdSec not only offers similar IP blocking capabilities but also enhances security by preventing port scanning and includes a Web Application Firewall (WAF).

Could we consider adding CrowdSec to the script?
