FormatNotSupported error on Windows 7

[raphlinus]

My code (https://github.com/raphlinus/synthesizer-io , just cargo run, see here for the code that sets up cpal playback) fails on my Windows 7 laptop with FormatNotSupported error.

I did some debugging, and the IsFormatSupported call is returning S_FALSE and the closest match the same as the request but with dwChannelMask filled in as 3 rather than 0. If I locally patch so that dwChannelMask in the request is initialized to 3, it works.

Hi @raphlinus I just left a comment here with my thoughts on no longer supporting Windows 7 in cpal going forward. I would love to hear your thoughts however!
