Camera controls temporary fix for head tracker users

There is a bug in War Thunder for those who have previously used FreeTrackNoIR and some other head tracking utility programs which prevents keyboard/hatswitch camera controls from working.

Those who wish to keep the software but not use the head tracking temporarily while using in-game keyboard camera controls needs to delete a specific DLL file temporarily.

Find and remove NPClient64.dll from opentrack/modules

The issue usually resolves immediately on windows 10 but you may need to restart the client for the change to take effect.
