feat: add bypass support methods to VentilationDevice and corresponding tests

[norschel]

This pull request adds support for retrieving detailed bypass status information from the ventilation device, along with corresponding unit tests to ensure these new methods work as expected.

New bypass status methods in PyViCareVentilationDevice:

• Added getBypassActive to check if the bypass is active.
• Added getBypassPosition to retrieve the current bypass position.
• Added getBypassAutomaticMode to determine if the bypass is in automatic mode.
• Added methods to get the bypass operating mode's level, state, and value: getBypassOperatingModeLevel, getBypassOperatingModeState, and getBypassOperatingModeValue.

Test coverage:

• Added unit tests in tests/test_VitoairFs300E.py for all new bypass status methods to verify correct behavior.This pull request adds support for retrieving the bypass status and configuration from the ventilation device, along with corresponding unit tests to ensure correct functionality.

Ventilation bypass feature support:

• Added getBypassActive, getBypassPosition, and getBypassAutomaticMode methods to PyViCareVentilationDevice.py to retrieve the bypass's active state, position, and automatic mode status, respectively.

Testing:

• Introduced unit tests for the new bypass methods (getBypassActive, getBypassPosition, getBypassAutomaticMode) in tests/test_VitoairFs300E.py to verify correct behavior.
