I believe punycode.decode("ls8h=") should be an error

I don't know the actual punycode algorithm, but based on the URL Standard test cases expecting https://xn--ls8h=/ to be an error, and jsdom/whatwg-url not passing this, I think the issue is with Punycode. punycode.decode("ls8h=") gives me "💧💩" instead of erroring.

/cc @karwa who seems to have enough of the Punycode algorithm in their head to be able to contribute fixes, potentially 🙏

I think I fixed this already 😊 - #124

When I try it on the RunKit NodeJS playground, the example does throw an error: https://runkit.com/embed/2b1uqmww0euj

Hmm, I was pretty sure I had updated my dependencies, but I guess not!
