feat: add IMU Python package with pybind11 bindings

- Add dm_imu_pkg/__init__.py to dynamically load compiled IMU module during development and installation
- Update .vscode/settings.json to ignore missing CMakeLists for flexible builds
- Generate egg-info metadata and package structure for distribution

+example.py – Demonstrates how to use the pybind11‑wrapped DM‑IMU driver.
+
+Prerequisites
+-------------
+* The compiled shared library `imu_py*.so` must exist (see README.md for build steps).
+* The current user must have read/write access to the IMU serial device
+  (e.g. /dev/ttyACM1).  Use `sudo` or add the user to the `dialout` group
+  if necessary.
+
+Usage

+$ python3 example.py
