[Suggestion] different headers for some files

Hi thanks for a great plugin,

I want to know how to set different headers for different files, is this possible ?

This could work nicely if it could be extended like this:

var defaultHeaders = {};

.pipe(publisher.publish(function(filepath) {
        // even better if it supported globs
	if (filepath === './dist/index.html') {
		return {
			'Cache-Control': 'max-age=315360000, no-transform, public'
		}
	}

        return defaultHeaders;
}))

I made this work by doing 2, with different cache file names, and then setting the index file that i want to add a different header. And in the second task only do file upload

gulp.task('copyIndexToS3', function() {
	// If the aws file are unavailable do nothing
	if (!awsKeys) {
		// To setup permissions, and policies check the article linked in the top
		console.log('Setup your aws keys, and bucket correctly guidelines are found in the link in gulp/cdn-s3.js file');
		return gulp.src('./dist/**');
	}

	var keysObj = live === true ? awsKeys.prod : awsKeys.dev;
	var publisher = awspublish.create(keysObj, {
		cacheFileName: '.awspublish-' + env + '.example.com-index'
	});
	return gulp.src([
			'dist/index.html'
		])
		.pipe(awspublish.gzip())
		.pipe(publisher.publish({
			'Cache-Control': 'no-cache, no-store, must-revalidate',
			'Expires': 0
		}, {
			createOnly: true
		}))
		.pipe(publisher.cache())
		.pipe(awspublish.reporter());
});

gulp.task('copyToS3', function() {
	// If the aws file are unavailable do nothing
	if (!awsKeys) {
		// To setup permissions, and policies check the article linked in the top
		console.log('Setup your aws keys, and bucket correctly guidelines are found in the link in gulp/cdn-s3.js file');
		return gulp.src('./dist/**');
	}

	var keysObj = live === true ? awsKeys.prod : awsKeys.dev;
	var publisher = awspublish.create(keysObj, {
		cacheFileName: '.awspublish-' + env + '.example.com'
	});

	return gulp.src([
			'dist/**',
			'!dist/index.html',
			'!dist/**/*.test*',
			'!dist/rev-manifest.json',
		])
		.pipe(awspublish.gzip())
		.pipe(publisher.publish({
			'Cache-Control': 'max-age=315360000, no-transform, public'
		}))
		.pipe(publisher.cache())
		.pipe(publisher.sync())
		.pipe(awspublish.reporter());
});
