opcua-server tool still depends on Eclipse Milo 0.6.16 — interest in upgrading to Milo 1.x?

[LivingLikeKrillin]

The plc4j/tools/opcua-server module still depends on Eclipse Milo 0.6.16
(dictionary-manager, sdk-server, and stack-server are all pinned to 0.6.16, and
dictionary-manager is a 0.6.x-only artifact).

Milo has since shipped 1.0 and is now on the 1.1.x line (latest 1.1.3); the 0.6.x series
is quite old. This would be a real migration rather than a version bump — between 0.6.x and
1.x, Milo:

• reworked/renamed pieces like DataTypeDictionaryManager → BinaryDataTypeDictionaryManager,
• moved several packages (e.g. sdk.server.api.config → sdk.server, sdk.server.api → sdk.server.items),
• changed the server bootstrap (1.x transport abstraction) and the cert/identity-validator APIs,
• and now requires Java 17+.

I'd be happy to take this on — I recently had a fix merged into Eclipse Milo itself and have
worked with its 1.x server SDK, so I've already mapped most of these API changes. Before I
start a PR, a couple of questions:

1. Is there interest in keeping this tool on a current Milo release?
2. Is there a specific reason it's still pinned to 0.6.16 (e.g. a minimum Java version for
   plc4x-extras I should respect)?

Happy to follow up with a PR if this is welcome.

I think there's always interest in improving things ... we're happy for any PR to help up improve things.

So ... are your still offering to update? Otherwise I'll probably close this issue soon.
