Build or find better way of pretty-printing arbitrary data to the browser console in CliRepl

[carnesen]

In Node.js, console.log

In the the browser currently we have a very hacky way of handling that:

cli/website/src/cli-repl.ts

Lines 173 to 188 in 9d807d4

	private consoleLog(arg: any) {
	if (typeof arg === 'string') {
	for (const ln of arg.split('\n')) {
	this.terminal.writeln(ln);
	}
	} else if (typeof arg === 'number') {
	this.terminal.writeln(yellow(String(arg)));
	} else if (typeof arg === 'object' && typeof arg.stack === 'string') {
	// Error object
	for (const line of arg.stack.split('\n')) {
	this.terminal.writeln(line);
	}
	} else {
	this.terminal.writeln(String(arg));
	}
	}

This enhancement is to find or build a library for doing that pretty-printing for us in the browser.
