📚 Description

When using getServerToken in a middleware the function returns null because it can't read the cookies. I changed your cookie parsing from the headers to using the h3 function parseCookies

Resolves #139

Was there a reason you parsed the cookies yourself instead of using the h3 parseCookies function?

It wasn't implemented properly in h3 when I created the module, but pretty sure it got fixed now.

The fix look good, but I need to find the time to test it as we don't have good test coverage set-up.

I would like to add that this does not solve getServerToken returning null on the server. Is there a workaround for getting the user's id?

@ferat Could you give #167 a try ? I believe this will resolve the issue and we'll close this PR.
