GST_AUDIO_API
gstaudiostreamalign: Pass self as const pointer in getter functions It was noticed in [1] that `GstAudioStreamAlign` is a simple boxed type that is passed as const in the copy function, but not as such in the getters. These functions turn out to be the only users of `const = true` overrides in `gstreamer-rs`. Since there is no locking or other advanced caching/sharing going on (as happens with miniobjects) these functions can safely take self as const pointer.
