Add Generic Parser Strategy for Table Format

[aep7128]

Generic Parser design here: https://app.diagrams.net/#G1ZhVaJu0XKpyKtDhr2uqTQVVWg-X07XC1

Generic Parser will use this strategy if it finds a source with a table layout (ex. https://www.qnap.com/en/security-advisories?ref=security_advisory_details)
