/**
* @summary Convert an image file into a `Uint8ClampedArray` of pixel data (RGBA).
*
* @function imageToUint8ClampedArray
* @async
* @description
* Reads an image file (PNG, JPEG, etc.) and returns its pixel data as a `Uint8ClampedArray`.
* Each pixel consists of four consecutive values: red, green, blue, and alpha (RGBA).
* Also returns the image's original width and height. Useful for canvas operations,
* image processing, WebGL textures, or computer vision tasks.
*
*
* @param {File} file - The image file to process. Must be a valid `File` object, e.g., from an `<input type="file">` element.
*
* @returns {Promise<{pixels: Uint8ClampedArray, width: number, height: number}>}
* A Promise resolving to an object containing:
* - `pixels`: A `Uint8ClampedArray` of RGBA pixel values.
* - `width`: Width of the image in pixels.
* - `height`: Height of the image in pixels.
*
* @throws {Error} Will not throw in current implementation, but could reject if the image fails to load.
*
* @example
* const fileInput = document.querySelector("#fileInput");
* fileInput.addEventListener("change", async (event) => {
* const file = event.target.files[0];
* const { pixels, width, height } = await imageToUint8ClampedArray(file);
* console.log("Width:", width, "Height:", height);
* console.log("Pixels:", pixels);
* });
*
* @todo Add error handling for invalid or corrupt image files.
* @variation Standard image file input
