Subject: [PATCH] Add Debian Trixie compatibility for pydub installation

This patch adds automatic detection and handling for pydub installation
on Debian Trixie systems where python3-pydub is not available due to
Python 3.13 removing the audioop module.

Changes:
- Removed direct python3-pydub installation via apt
- Added logic to detect if python3-pydub is available in system packages
- Falls back to installing audioop-lts and pydub via pip when system
  package is unavailable (required for Python 3.13 compatibility)

This ensures SkywarnPlus works correctly on both Debian Bookworm (where
python3-pydub is available) and Debian Trixie (where it must be
installed via pip).
