Ville Vesilehto 2f9f30934a test(request): improve coverage across package (#7307)
Add tests for previously untested functions:
- edns0.go: test supportedOptions function
- request.go: test address methods, protocol handling, and EDNS0
  options
- writer.go: test ScrubWriter implementation

Improves overall package test coverage from 39.5% to 77.8%.
