Fallback to standard img when src is a string

[asjir]

When dealing with sources that may or may not be processed by svelte-img we currently have:

{#if typeof image === "string"}
  <img src={image} alt={title} class="w-full h-48 object-cover" />
{:else}
  <Img src={image} alt={title} class="w-full h-48 object-cover" />
{/if}

which, granted, is not that bad.

But it makes me wonder if it wouldn't be better to include switch on the typeof image inside the Img component?
