Summary
This PR adds staged rendering caches for HiFiUTAU. Raw synthesis, HN-SEP processing, and post-processing parameters such as tension, breathiness, and voicing are cached separately. This significantly reduces synthesis time when adjusting post-processing parameters and lowers rendering resource usage.
Discussion point
Cached WAV files are now written as float32 instead of PCM16. This may cause some changes in perceived audio quality and should be evaluated before merging.
