Is there an adequate replacement for deprecated `LoginResult` field?

[Integralist]

The public LoginResult field is marked as deprecated but is still actively used by the package itself (specifically the public Login method writes to this field)...

https://github.com/domainr/epp/blob/main/conn.go#L45-L46

What is the upgrade path for an application using the value assigned to LoginResult?

@Integralist - wondering if we need to do anything here? It's been a few years 😅
