Reasoning: The `data` parameter in `QuantizeLevels` (defined in `src/utils/quant_levels_utils.c` line 33) was causing bounds safety errors because it was accessed using array subscripts (e.g., `data[n]` at lines 60-63 and 137) but was typed as a single pointer. The size of the buffer pointed to by `data` is determined by the `width` and `height` parameters, calculated as `data_size = height * width` at line 39. The loops accessing `data` iterate up to `data_size`. To fix this, the `data` parameter in both the function definition and its declaration (`src/utils/quant_levels_utils.h` line 30) was annotated with `WEBP_COUNTED_BY((size_t)width * height)`.

WebP codec is a library to encode and decode images in WebP format. This package contains the library that can be used in other programs to add WebP support, as well as the command line tools 'cwebp' and 'dwebp' to compress and decompress images respectively.
See https://developers.google.com/speed/webp for details on the image format.
