Breaking changes:

• Replaced the buffer_size option in CpalBackendSettings with config, which gives many more configuration options (thanks @DaforLynx!)
• Switch to 2024 edition, update dependencies, and update GitHub actions to use newer rustc versions (thanks @Roms1383!)
• Remove the android_shared_stdcxx feature, as cpal now uses ndk::audio, and cpal's oboe-shared-stdcxx feature is deprecated

Other changes:

• Switch from paste to pastey, re-export pastey, and update macros to not require manually importing pastey at the call site (thanks @Keinsleif!)
• Fix typo in readme (thanks @benjamin-lieser!)
