Whitelisting by subnet does not work

[delameter]

Hello. Plugin's config reading fails with an error "not valid".

Prerequisites:

Traefik version 2.9.5 fail2ban version v0.6.6

middlewares.yml:

http:
  middlewares:
    mw-fail2ban:
      plugin:
        fail2ban:
          rules:
            bantime: 1h
            findtime: 1s
            enabled: true
            maxretry: 50
            ports:
              - 443
          blacklist:
            ip: []
          whitelist:
            ip:
              - 192.168.1.0/24

The result:

$ docker-compose up traefik 
Starting dup-traefik ... done

Suggestions

After looking through ipChecking.go I can assume that the problem is around line 46 -- according to docs, net.ParseIP does not expect a subnet in an input string, that's what net.ParseCIDR is for.
