d14395bc5db55331115fa3c1e71741d1de7f092f net, doc: provide context for UnserializeV1Array() (Jon Atack)
Pull request description:
Add contextual documentation for developers and future readers of the code regarding
- CNetAddr::UnserializeV1Array (see #22140)
- Span and why it defines Clang lifetimebound locally rather than using the one in attributes.h
