 Once the context has been initialized you can initialize a device. Before doing so, however, the application may want to know which
 physical devices are available. This is where `onContextEnumerateDevices()` comes in. This is fairly simple. For each device, fire the
 given callback with, at a minimum, the basic information filled out in `ma_device_info`. When the callback returns `MA_FALSE`, enumeration

 Detailed device information can be retrieved from a device ID using `onContextGetDeviceInfo()`. This takes as input the device type and ID,
 and on output returns detailed information about the device in `ma_device_info`. The `onContextGetDeviceInfo()` callback must handle the
