Rollup configuration is missing the svelte preprocess plugin

[karmaral]

Hello.
I've recently stumbled into an issue when trying to use svelte-french-toast. The styling was misbehaving, and when investigated on their end, it turned out to be a missing option in the rollup configuration. The style: directives were not being applied because of the missing sveltePreprocess plugin.

Here's a link to the issue

And here you can see a fork of my repo with the fix

If you'd like I could make a PR addressing this.
