Issue Description

After the (automatic) update to 2.19.1, the previously recorded bag files don't work anymore. When attempting to open them I get:

Failed to load file /home/houjebek/code/pats/pc/build-pc-Desktop-Debug/throughtheroof/test.bag. Reason: Io in rs2_context_add_device(ctx:0x55ef1b48dd30, file:/):
Failed to create ros reader: Unrecognized sensor nameMotion Module

These bag files were recorded with SDK 2.18.1, and they were confirmed to be working before the update to 2.19.1. Unfortunately, they are quite big files so I cannot easily share them.

We should maintain backward-compatibility in regards to bag format.
I believe it was tested, but let me check with D435i specifically

Jup, that fixes it. Tnx!
