[Feature proposal] Get channel names of a device for certain platforms

[nico-franco-gomez]

Some hosts such as CoreAudio or ASIO support having string names for each input/output channel of a device (besides their index). So far, I have not seen this functionality implemented in CPAL, but it would be very useful for a project where users can select input or output channels based on their names rather than the index. Is this a feature that would be worth implementing? Is there maybe a reason why this hasn't been done yet?

Hello! I went ahead and wrote some code for a project where the channel names are provided for the aforementioned hosts. Would it be of interest here, even though it may not be available to all platforms? If so, I could start a PR with this functionality since more people might find it useful
