0.7.19 — Accurate stream metadata (wraps neolink 0.7.17)

0.7.19

Wraps neolink 0.7.17. Makes each camera's reported frame rate, bitrate and resolution match its actual current settings.

• The add-on used to read these from a camera "capability" list whose frame rate and bitrate are factory defaults that don't follow what you've actually configured — so a sub stream set to 15 fps could be cached as 10, and a main stream could report the wrong bitrate or resolution. It now reads the camera's current encoder settings directly, so the values are correct.
• This is an internal accuracy fix: your live video always played at the true rate; only the reported/cached metadata was off. If a camera was cached with a wrong value by an earlier version, it corrects itself the first time you open that camera after updating.

No add-on configuration changes are required.
