[bug] Crowdsec crash if nginx log contains IPv6

[thelittlefireman]

Hi,
On last dev version the lua script crash due to the fact that nginx log contains an ipv6 :

crowdsecurity/lua-cs-bouncer#7

2020/12/28 21:59:25 [error] 9518#9518: *80 lua entry thread aborted: runtime error: /usr/local/lib/lua/crowdsec/CrowdSec.lua:18: attempt to perform arithmetic on local 'o1' (a nil value)#012stack traceback:#012coroutine 0:#012#011/usr/local/lib/lua/crowdsec/CrowdSec.lua: in function 'ipToInt'#012#011/usr/local/lib/lua/crowdsec/CrowdSec.lua:70: in function 'allowIp'#012#011access_by_lua(main-lua.conf:166):105: in main chunk, client: 2a01:e0a:169:7f90::d73a:9b9d, server: nextcloud.mydomain, request: "PROPFIND /remote.php/dav/files/user/ HTTP/1.1", host: "nextcloud.mydomain"

original nginx log :

==> /var/log/access.log <==
2a01:e0a:169:7f90::d73a:9b9d - user nextcloud.mydomain [28/Dec/2020:21:59:25 +0100] "PROPFIND /remote.php/dav/files/user/ HTTP/1.1" 500 170 "-" "Mozilla/5.0 (Linux) mirall/3.1.1-20201225.075704.75c329f4f-1.0~groovy1 (Nextcloud)"

Should we wait lua script to be updated or do you need some help to make a quick bugfix ?
