v0.0.17 is incompatible with newer Svelte

[soeroesg]

The latest released version v0.0.17 seems to be incompatible with new Svelte because a method got renamed in Svelte.

Projects using thumb-ui and built with recent Svelte version will fail loading with the following error:
https://127.0.0.1:8080/_snowpack/pkg/thumb-ui.v0.0.17.js [:1:358]
SyntaxError: The requested module '/_snowpack/pkg/svelte.internal.v3.59.1.js' does not provide an export named 'add_resize_listener'

In fact, the Svelte method was renamed to 'add_iframe_resize_listener'

I believe recompiling the package with a newer Svelte and republishing it would solve this issue.
