Install buffer and add a fallback to retain original behavior.

Note that this increases the overall bundle size, so increase the
bundlesize check by an additional 1kB.

Original error message that showed before these changes:

	webpack < 5 used to include polyfills for node.js core modules by default.
	This is no longer the case. Verify if you need this module and configure a polyfill for it.

	If you want to include a polyfill, you need to:
		- add a fallback 'resolve.fallback: { "buffer": require.resolve("buffer/") }'
		- install 'buffer'
	If you don't want to include a polyfill, you can use an empty module like this:
		resolve.fallback: { "buffer": false }
