AccessListParser

Groups all ACL entries under a parent ip access-list header.

• Location: parsers/access_list_parser.py
• Captures ip access-list standard|extended header.
• Uses the following parsing sequence:
  • First pass: capture the header name and type.
  • Second pass: parse each sequence (10 permit, 20 deny, 30 remark, etc.), modeling protocol, qualifiers, IPs, masks, and ranges.

• Outputs one ParsedLine per ACL with all entries inside.

• Challenge: maintaining sequence numbers and understanding components of access lists (why some lines include two IP addresses, tcp vs udp vs icmp protocols, etc)
