[BUG]: LogoX too small and always black

### Description of the bug Thanks for the awesome library! I happened to notice that LogoX seems to be too small, and always black. ### Steps To Reproduce Just use the LogoX icon anywhere: ```svelte <LogoX /> ``` Is also reproduced in the demo site: https://svelte-ionicons.codewithshin.com/icons ### Additional Information In browser dev tools I scaled the viewBox from `0 0 512 512` to `0 0 16 16` (32x bigger), and this seemed to scale the icon to the proper size. The color problem seems to go away when changing `fill="black"` to `fill="currentColor"`.
