An Xsens MVN Analyze support module for HERMES

HERMES - Xsens MVN Analyze

Support package to interface the Xsens IMU MoCap commercial system of Xsens/Movella in HERMES via the Network Streamer plugin.

[!NOTE] Xsens MVN Analyze is a full-body system of wearable IMUs, and a receiver base station connected to a Windows PC, with a practical range of ~20 meters. Lost packets degrade fitting of the biomechanical model to the person. Ensure the person stays in range or the base station is moved around for this device.

[!WARNING] Xsens MVN Analyze <2024.* had some bugs in the Network Streamer plugin, causing ~30-50% packet dropout. We suggest to use >=2024.*.
