Reflect prop changes to the tooltip

BugFix: #6

TippyStore for programatically usage

If the anchorNode defines the "id" attribute, the instance is added to svelte store which is exported by
tippyStore.ts/tippyStore.js

<script>
	import {tooltip, popover} from "../../../index";
	import {tippyStore} from "../../../tippyStore";
	import MyTooltip from './MyTooltip.svelte';
	export let name;

	$: console.log($tippyStore);
</script>

<main>
	<h1 use:tooltip={{component: MyTooltip}}>Hello {name}!</h1>
	<p>Visit the <a href="https://svelte.dev/tutorial">Svelte tutorial</a> to learn how to build Svelte apps.</p>
	<div id="popover" use:popover={{component: MyTooltip, props: {title: 'my test title', content: 'My test content'}}} >
  Hover
</div>

In this the example is stored in $tippyStore.popover and can be used in this way

$tippyStore.popover.show();
