Add to JSR registry

[D-Byte]

Please can you add your package to the JSR registry for Deno, it will make integrating socket.io Deno package easier.

I need to depend on this in a JSR package, which isn't possible without publishing socket.io-deno to either JSR or NPM.

Since packages published to JSR can still be included over HTTP like they can on deno.land/x this shouldn't impact existing users negatively I don't think.

Would you be open to a PR to migrate to JSR?
