toktx's ceilMultipleOfFour breaks on numbers with small fraction

[upisfree]

This code will break on numbers with small fraction:

glTF-Transform/packages/cli/src/transforms/toktx.ts

Lines 467 to 470 in 8bbdd5e

	function ceilMultipleOfFour(value: number): number {
	if (value <= 4) return 4;
	return value % 4 ? value + 4 - (value % 4) : value;
	}

I found this solution working for this case:

@upisfree are there parameters to the library that make the input to ceilMultipleOfFour a non-integer? Is this while resizing an image, for example?

No, I used just this function outside of the gltf-transform, found this and thought that maybe same situation can occur in gltf-transform.
I had this issue when I tried to resize and keep an aspect ratio of the image (for converting it to ktx2 later). For example, image with resolution 255x256 caused and issue in my case.
