Recent release of svelte breaks this plugin

[maraisr]

There seems to be a "autoload" method doing:

function autoload() {
	const pkg = require('svelte/package.json');
	const version = to_major(pkg.version);

	const { compile, preprocess } = require(version >= 3 ? 'svelte/compiler.js' : 'svelte');
	return { compile, preprocess, version };
}

which seems to complain like:

Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './compiler.js' is not defined by "exports" in /node_modules/svelte/package.json

node: 15.0.1
yarn: 1.22.5
svelte: 3.29.7
rollup-plugin-svelte: 6.1.0
svelte-preprocess: 4.6.0

There's no rollup-plugin-svelte@1.4.1, so I'm not sure what version you're really using - but this was already fixed in rollup-plugin-svelte 6.1.1 via #151.

My apologizes @Conduitry it was meant to read: 6.1.0. Have updated.
