Inconsistent IMU information

[peci1]

• OAK-D has no IMU in boards/ but it has one in https://github.com/luxonis/depthai-ros/blob/3170e8773aea8066beae4433c71cfce9145306e2/depthai_descriptions/urdf/include/base_macro.urdf.xacro#L72 and in shop it shows BNO085
• OAK-D Lite has both BMI and BNO IMUs in boards/ JSON, but it shows a 6-axis IMU in tech specs on https://shop.luxonis.com/products/oak-d-lite-1 and 9-axis IMU in the image with features on the same page
• OAK-T has no IMU in boards/ JSON, but it shows one in https://docs.luxonis.com/hardware/products/OAK%20Thermal#IMU
• All OAK4 cameras have no IMU in boards/ JSON but tell to have one on the shop pages
  • Here, it'd make sense to enlist both the offset of the IMU and the offset of the magnetometer which is said to be separate.
