Support kernel option in resize

[kyranet]

Describe the feature

Right now, the library defines three options (out of many):

ipx/src/handlers/handlers.ts

Lines 98 to 102 in b912370

	return pipe.resize(width, height, {
	fit: context.fit,
	position: context.position,
	background: context.background,
	});

The kernel option allows us to set one of nearest, cubic, mitchell, lanczos2, and lanczos3, which by default uses the last one. However, for pixel art, this is far from ideal, as it blurs the pixels.
