Allow access to api

[roydukkey]

As a user of the component, I would like to be able to download the data as a CSV.

Would it be as simple as changing the following from:

svelte-ag-grid/src/Component.svelte

Line 25 in 9d19c4c

let api;

to:

export let api;

Or, is there a better solution?

Implementing #9 might be a better option for this issue, as it would allow the consumer to write something like this to access the APIs.

<script>
	import AgGrid from "@budibase/svelte-ag-grid";

	let data = [
		{ make: "Toyota", model: "Celica", price: 35000 },
		{ make: "Ford", model: "Mondeo", price: 32000 },
		{ make: "Porsche", model: "Boxter", price: 72000 },
	];

	let columnDefs = [
		{
			headerName: "Make",
			field: "make",
			sortable: true,
			editable: true,
		},
		{ headerName: "Model", field: "model", sortable: true },
		{ headerName: "Price", field: "price", sortable: true },
	];

	let api;

	let options = {
		onGridReady: (params) => {
			api = params.api;
		}
	}

	function download () {
		if (api) {
			api.exportDataAsCsv({
				fileName: 'downloadFileName.csv',
				columnGroups: true
			});
		}
	}

</script>

<style>
	:global(:root) {
		--grid-height: 500px;
	}
</style>

<AgGrid bind:data {columnDefs} {options} />

<button on:click|preventDefault={download}>Download Data</button>
