Fix issue #1574: Add location accuracy filter to prevent GPS drift

[Ahmed-Makled]

Description

This PR addresses issue #1574 by implementing a location accuracy filter to prevent random GPS drift which can cause erratic movement patterns in tracking applications.

Changes

• Added LocationAccuracyFilter class to filter out location updates with physically implausible movement patterns
• Implemented filtering based on accuracy, speed, and distance thresholds
• Added enableAccuracyFilter parameter to AndroidSettings class
• Added unit tests for different transportation modes and edge cases
• Updated documentation and CHANGELOG.md

Implementation Details

The filter works by:

• Detecting locations with very poor accuracy (> 300 meters)
• Filtering unrealistically high speeds (> 280 m/s or ~1000 km/h)
• Identifying large position jumps when combined with poor accuracy values
• Providing a configurable approach that doesn't interfere with legitimate use cases

Testing

The implementation includes comprehensive tests for:

• Standard walking/driving scenarios (accepted)
• High-speed transportation like trains (accepted)
• Unrealistic movements like teleportation (rejected)
• Different accuracy values and edge cases

This solution is designed to be minimally invasive, with filtering disabled by default to maintain backward compatibility.
