WindowFilter duration based on movement speed

[Steppschuh]

The sliding window filters used for signal cleaning could have a dynamically sized window, depending on the current movement speed.

If we detect that the device is not moving (or very slowly moving), we could increase the window duration (e.g. to 10 seconds). That would result in a more stable multilateration result.

If we detect that the device is moving, we could decrease the window duration (e.g. to 3 seconds). That would result in less delay of the multilateration result.
