Summary

I have a set of scans where I encode some data in the probe, similar to how zmap's UDP templating works
I currently have a custom module for this, but am aiming to retire it by contributing back a bigger set of changes to zgrab2 proper

Changes

• Add --expand-probe without changing existing static-probe behavior.
• Support the full ZMap UDP template macro set, including socket addresses and ports, random values, hexadecimal bytes, Unix timestamps, and NTP timestamps.
• Preserve unknown template fields literally, matching ZMap behavior.
• Expand connection-dependent fields from the established socket and explicitly reject IPv4 network-order address fields on IPv6 connections.
• Document template syntax, byte encodings, and examples.
• Add parser, expansion, validation, IPv4/IPv6, file-probe, inline-probe, and scanner integration tests.

Testing

• go test ./modules/banner
• go test -race ./modules/banner
• golangci-lint run ./modules/banner/...
• go test ./...
• Built cmd/zgrab2 and inspected zgrab2 banner --help
