Add sound modes to Bang & Olufsen devices

[mj23000]

Proposed change

Add sound mode selection to the media_player entity.

The Bang & Olufsen App allows users to create sound modes with identical names, which is problematic because Home Assistant only uses a string is used to determine selection, which makes it impossible to determine the selection of two identically named sound modes.

Therefore the unique ID of the sound mode has been appended to the sound mode's name in Home Assistant.
For example: the test sound mode is now called test - 100.

For example: the test sound mode is now called test - 100.

Would it not be prettier with brackets?
test (100)
