Add ES512 support

[Xuanwo]

Hi,

databendlabs/databend#5062 needs ES512 support from jsonwebtoken.

Is there anything special to take care of? I'm willing to submit a PR to add ES512 support 🚀

First you need add P-512 to ring briansmith/ring#824

This would be a great improvement 🙂

Seems like there is an active PR to add support for this in ring. briansmith/ring#1631

Please add ES512, we are blocked too

I think it will be available after #410
