Support Forward looking Regex used in uBO

```
/^https?:\/\/(?:[a-z]{2}\.)?[0-9a-z]{5,16}\.[a-z]{3,7}\/[a-z](?=[a-z]{0,25}[0-9A-Z])[0-9a-zA-Z]{3,26}\/\d{3,6}(?:[?&][_a-z0-9]+=[-0-9a-zA-Z]+)*$/$script,3p,redirect-rule=noop.js,match-case
```

The lookahead is unsupported: `(?=[a-z]{0,25}[0-9A-Z])`

Probably a seperate issue:

```
/\/[0-9a-z]{2}\/[0-9a-f]{32}\.js/$script,3p,match-case,method=get,from=~edu.ag|~edu.by|~edu.bz|~edu.ge|~edu.in|~edu.md|~edu.me|~edu.pe|~edu.pk|~edu.so|~edu.ws|~gov.ag|~gov.by|~gov.bz|~gov.ge|~gov.in|~gov.md|~gov.me|~gov.pk|~gov.sh|~gov.so|~gov.to|~gov.tv|~gov.ws|~palaugov.pw|~proton.me|~twitch.tv|ad|ag|app|bet|biz|blogspot.com|blue|boo|by|bz|casa|cash|cc|ceo|cfd|click|club|com.se|cx|cyou|dad|day|dev|download|forum|fun|gdn|ge|hair|homes|host|how|icu|in|info|is|lat|link|live|lol|ltd|md|me|media|mobi|moe|monster|one|onl|online|page|pe|pk|pro|pw|re|red|rest|sbs|sh|site|skin|space|stream|team|tel|to|today|top|tube|tv|wedding|world|ws|xyz,to=com

Believe the `to=com` is unsupported
