dr_wav.h W64 CUE Chunk Metadata Parsing Integer Overflow Leading to Heap Buffer Overflow on 32-bit Builds

dr_libs dr_wav.h (all versions through current master) contains an integer overflow in W64 CUE chunk metadata parsing. In drwav__metadata_process_chunk, a stage-1 capacity estimate truncates the 64-bit W64 chunk sizeInBytes to size_t before dividing by DRWAV_CUE_POINT_BYTES; on 32-bit builds this truncation causes the pre-allocated extra metadata capacity to be computed incorrectly.
