feat: extract IMU from GoPro videos

[ptpt]

This pull request introduces significant changes to the mapillary_tools/geotag/gpmf_parser.py file, focusing on enhancing telemetry data extraction and handling. The most important changes include the addition of new functions for matrix calibration and telemetry data extraction, as well as updates to existing functions to accommodate these enhancements.

Enhancements to telemetry data extraction:

• mapillary_tools/geotag/gpmf_parser.py: Added new functions _is_matrix_calibration, _build_matrix, _apply_matrix, _flatten, _get_matrix, _scale_and_calibrate, _find_first_telemetry_stream, and extract_telemetry_data to support telemetry data extraction and processing. [1] [2]
• mapillary_tools/geotag/gpmf_parser.py: Updated _extract_points_from_samples to extract and interpolate accelerometer, gyroscope, and magnetometer data in addition to GPS points.

Refactoring and code improvements:

• mapillary_tools/geotag/gpmf_parser.py: Refactored imports and replaced sample_parser with TrackBoxParser, MovieBoxParser, and Sample for better code clarity and structure.
• mapillary_tools/geotag/gpmf_parser.py: Modified extract_points to use the new telemetry data extraction functions and added extract_telemetry_data for comprehensive telemetry data retrieval.

Addition of new data structures:

• mapillary_tools/imu.py: Introduced GyroscopeData, AccelerationData, and MagnetometerData classes to represent gyroscope, accelerometer, and magnetometer readings respectively.

Test updates:

• tests/cli/gpmf_parser.py: Added _parse_samples function to parse and dump telemetry samples for testing purposes, and updated the main function to utilize this new function for sample dumping. [1] [2] [3] [4] [5]
