enhanced-img: Support configuring vite-imagetools (e.g. removeMetadata=false)

[SpraxDev]

Describe the problem

I would like to keep the exif metadata information stored in my images, but when using enhanced-img, these are removed by-default.

vite-imagetools supports removeMetadata which is true by default (which I think is a good default).

Describe the proposed solution

accept a list of options in

kit/packages/enhanced-img/src/index.js

Line 9 in 42c8bf3

export function enhancedImages() {

that might be passed into vite-imagetools:

kit/packages/enhanced-img/src/index.js

Lines 64 to 66 in 42c8bf3

	function imagetools_plugin() {
	/** @type {Partial<import('vite-imagetools').VitePluginOptions>} */
	const imagetools_opts = {

You might not want to just accept all options and just blindly pass them to vite-imagetool, but maybe a list of sensible parameters might make sense.

Alternatives considered

I couldn't find any alternative while sticking with sveltejs/enhanced-img.
I'd need to switch to another package

Importance

nice to have

Additional Information

Remeber to delete node_modules/.cache/imagetools, when testing the removeMetadata option.
