expose contexts

[c19]

So that other component can act on route changes

[JohnnyFun]

As a workaround, you can import it directly from node_modules like kysonic points out here: #41

import {getContext} from 'svelte';
import {ROUTER} from 'svelte-routing/src/contexts';
const { activeRoute } = getContext(ROUTER);

$: {
    console.log($activeRoute)
 }
