v0.6.0 beta 6

• Moved the functionality from kira-cpal and kira-loaders into the main kira crate. kira-cpal and kira-loaders are now unneeded and deprecated.
  • CpalBackend from kira-cpal is now available as kira::manager::backend::cpal::CpalBackend
  • kira_loaders::load and kira_loaders::load_from_cursor are now StaticSoundData::from_file and StaticSoundData::from_cursor
  • kira_loaders::stream and kira_loaders::stream_from_cursor are now StreamingSoundData::from_file and StreamingSoundData::from_cursor
• Added Renderer::on_change_sample_rate, which the Backend should call if the audio sample rate changes
• Added Effect::on_change_sample_rate, which is called when the audio sample rate changes
• Changes to the Backend trait:
  • Added the associated type Backend::settings and the method Backend::setup, which is used for creating Backends (basically a new function, but required by the Backend trait)
  • Renamed Backend::init to Backend::start
  • Removed Backend::sample_rate
  • Removed UnusedResourceCollector from the public API. Backends are no longer responsible for dropping unused resources.
• Updated MockBackend to the new API
• Removed the backend argument to AudioManager::new
• Restructured AudioManagerSettings
• The cpal backend will now do its best to gracefully handle device disconnection and sample rate changes
• The cpal backend now works in wasm environments
