... in order to make standard containers be able to store it. Required for #5532 (#4899) and the recording PR. This includes: * removing the `LocklessRingBuffer<sampleFrame>` specialization * passing samplerame in `StereoDelay::tick` as a reference Additional cleanups: * removing already unused typedef `sampleFrameA` * add some `const_cast` to make code more readable
