[HoloAdventure]

• OverView

I updated the plugin and UnitySample to get LONG THROW depth Data

I added the following API for LONG THROW depth Data to the plugin ・InitializeLongDepthSensor() ・StartLongDepthSensorLoop() ・LongDepthMapTextureUpdated() ・GetLongDepthMapBuffer() ・GetLongDepthMapTextureBuffer() ・GetLongDepthBufferSize()

I added drawing area for LONG THROW depth Data to UnitySample. And I added the function to get LONG THROW depth Data to ResearchModeVideoStream.cs.

• How to check

The plugin in UnitySample has been replaced with the plugin of LONG THROW depth Data. Follow the Readme instructions to deploy to HoloLens2.

• Code validity

The conversion logic from LONG THROW depth Data to grayscale is based on the code of HoloLens2ForCV. Same as lines 266 to 307 of SlateCameraRenderer.cpp below. https://github.com/microsoft/HoloLens2ForCV/blob/main/Samples/SensorVisualization/SensorVisualization/Content/SlateCameraRenderer.cpp
