Adds two non-owning views for audio buffers: `InterleavedBufferView` and `PlanarBufferView`. The channel count can be specified at either compile-time or runtime. Specifying at compile-time provides both performance and space optimizations. The way this works is the same as `std::span` except this uses the new `DynamicChannelCount` constant rather than `std::dynamic_extent`.
