ImageKit aspectRatio param double encoding

[maybephilipp]

ImageKit operation for aspectRatio (ar) url-encodes value twice.

Input:

{
  imagekit: {
    ar: '9-16'
  }
}

Output: https://ik.imagekit.io/image.png?updatedAt=1778956861259&tr=ar-9%252D16%2Cfo-custom%2Cw-640%2Cc-maintain_ratio

You can see ar-9%252D16 which is:

decodeURIComponent(decodeURIComponent('ar-9%252D16')) === 'ar-9-16'  // true
decodeURIComponent('ar-9%252D16') !== 'ar-9-16'  // false – 'ar-9%2D16'

This breaks ImageKit's aspect ratio functionality.

P.S. Yes, correct syntax for aspect ratio in ImageKit is dashed, not semicolon.

I tried to overcome this bug using transformer, but in @unpic/svelte this param (custom transformer) is completely ignored (https://github.com/ascorbic/unpic-img/blob/0128fb084010f30808ec334a1637bb47638ad517/packages/core/src/auto.ts#L64-L90 , https://github.com/ascorbic/unpic-img/blob/0128fb084010f30808ec334a1637bb47638ad517/packages/svelte/src/lib/source.svelte#L9).

I guess, the best way is to write my own Svelte support.
