gVisor bot d6dc5ba19c feat: support sub-rule, eg.
rules:
  - SUB-RULE,(AND,((NETWORK,TCP),(DOMAIN-KEYWORD,google))),TEST2
  - SUB-RULE,(GEOIP,!CN),TEST1
  - MATCH,DIRECT

sub-rules:
  TEST2:
    - MATCH,Proxy
  TEST1:
    - RULE-SET,Local,DIRECT,no-resolve
    - GEOSITE,CN,Domestic
    - GEOIP,CN,Domestic
    - MATCH,Proxy
