--update-references could maybe create the reference directory

[martinRenou]

When running --update-references for the first time, the command fails with:

Reference directory './reference-output' does not exist.
error Command failed with exit code 1.

Maybe Galata could automatically create the reference directory if it doesn't exist?

Looks like this might be coming from:

galata/packages/galata/bin/cli.js

Lines 447 to 450 in 6dd96e9

	if (!fs.existsSync(outputDir)) {
	console.log(`Output directory '${outputDir}' does not exist.`);
	process.exit(1);
	}

Maybe this could indeed be replaced by automatically creating the directory instead.
