Add video download functionality and update video info

- Updated `Program.cs` in `Blink.ConsoleTest` to iterate over videos and print byte array lengths.
- Added `GetVideoAsync(BlinkVideoInfo video)` method in `BlinkClient.cs` to download video clips.
- Modified `GetVideosAsync` in `BlinkClient.cs` to set `NetworkId`, `ModuleId`, and `ManifestId` for each video.
- Added `NetworkId`, `ModuleId`, and `ManifestId` properties to `BlinkVideoInfo.cs` with `[JsonIgnore]` attribute.
