* Use BlueZ DBus ObjectManager for device discovery. * Replace subprocess calls to hcitool with native dbus communication. * Implement discovery and adapter management via org.bluez interfaces. * Add support for identifying DualSense and newer controller variants. * Modernize Python syntax (f-strings, super()) and improve error handling. * Remove dependency on deprecated bluez-utils (hcitool). * Update socket management and class inheritance to modern Python standards. * Fix crashes on systems where hcitool is not available.
- Implemented UDP telemetry for battery levels on port 54321, allowing integration with external tray monitors. - Added graceful handling for 'BrokenPipeError' when reading Bluetooth MAC addresses via hidraw (fixes crashes on modern kernels). - Added try/except blocks for device grabbing to prevent initialization failures when the kernel driver is already active. - Reduced battery check interval to 5 seconds for more responsive reporting.

Motivation:
hcitool and hciconfig are deprecated in BlueZ 5 and removed from many modern Linux distributions (like openSUSE, Fedora, and Arch).
Changes:
Switched from subprocess to python-dbus.
Implemented StartDiscovery and StopDiscovery via DBus.
Improved device filtering (now catches "DualSense" and "DualShock").
Refactored the main loop to be less aggressive and use time.sleep().
