sceNgs2ParseWaveformFile read everything from the offset to the end of the file into a zero-filled buffer and parsed that, although parsing uses only the RIFF chunk headers and the fmt, fact and smpl payloads. A waveform at an offset in a sound bank cost a read of the rest of the bank on each call. ReadChunks now takes the bytes through an accessor. Waveform data passes its buffer; a waveform file seeks to and reads the headers and those payloads alone, with the same checks against the length from the offset to the end of the file. The format dispatch both use moves to ParseWaveform. ngs2_parse adds a bank of two waveforms in one file, the second with a chunk after its samples, and parses each at its offset. PPSA21402 (Balatro) parses its five 33 MB music tracks at start: one call took 8.3 to 26.7 ms and allocated 33 MB, and now takes 0.01 to 0.04 ms with the same result.
