Using DeinterleavedView<> simplifies these two classes, so now the classes are arguably thin wrappers on top of DeinterleavedView<> and AudioFrameView<> can be replaced with DeinterleavedView<>. The changes are: * Make VectorFloatFrame not use a vector of vectors but rather just hold a one dimensional vector of samples and leaves the mapping into the buffer up to DeinterleavedView<>. * Remove the `channel_ptrs_` vector which was required due to an issue with AudioFrameView. * AudioFrameView is now a wrapper over DeinterleavedView<>. The most important change is to remove the `audio_samples_` pointer, which pointed into an externally owned pointer array (in addition to the array that holds the samples themselves). Now AudioFrameView can be initialized without requiring such a long-lived array.
