0.7.17 — Live-view reliability (wraps neolink 0.7.15)

Wraps neolink 0.7.15. Fixes Home Assistant live view dropping into a reconnect loop.

• Some cameras' live view would connect and then immediately drop, retrying every few seconds and never showing video — most noticeable after a camera briefly fell behind or reconnected. While a camera was connecting, Neolink filled the gap with a placeholder frame whose video parameters didn't match the camera, so Home Assistant's player (go2rtc) rejected the real stream the moment it took over. Neolink now reuses the camera's own most recent frame for that placeholder, so the live picture takes over cleanly and the stream stays up.
• Live view also recovers faster when a camera momentarily falls behind: the stream now catches up to the latest frames instead of staying stuck replaying a backlog.

No add-on configuration changes are required to keep today's behaviour.

See the neolink 0.7.15 release for the underlying technical details.
