feat: add IMU data in CAMM as experimental feature

[ptpt]

This pull request includes significant changes to the mapillary_tools package, primarily focused on enhancing the handling and processing of telemetry data. The most important changes are the introduction of new telemetry data types, refactoring of existing functions to support these new types, and updates to various modules to integrate the new telemetry data handling.

Telemetry Data Handling Enhancements:

• mapillary_tools/camm/camm_builder.py: Refactored to support new telemetry data types (AccelerationData, GyroscopeData, MagnetometerData) and updated functions to handle these types. This includes the addition of the TelemetryMeasurement union type and the _multiplex function for combining different telemetry measurements. [1] [2] [3] [4] [5]

• mapillary_tools/camm/camm_parser.py: Added parsing support for new telemetry data types and updated the extract_points and filter_points_by_elst functions to handle these types. Introduced the extract_telemetry_data function to extract all telemetry data from a CAMM video. [1] [2] [3] [4] [5]

Integration of Telemetry Data Types:

• mapillary_tools/geotag/gpmf_parser.py: Updated to replace the old IMU data types with the new telemetry data types. This includes changes in the TelemetryData class and the _extract_points_from_samples function. [1] [2] [3] [4] [5] [6]

• mapillary_tools/telemetry.py: Introduced new telemetry data classes (TelemetryMeasurement, AccelerationData, GyroscopeData, MagnetometerData) to replace the old IMU data classes.
