Support Cookie 1.x

[MikaKarjunen]

Is your feature request related to a problem? Please describe.
If for some reason cookie 1.x is installed the compilation fails with following error message.
node_modules/engine.io/build/server.d.ts:4:15 - error TS2724: '"cookie"' has no exported member named 'CookieSerializeOptions'. Did you mean 'SerializeOptions'?

Describe the solution you'd like
Obviously something needs to change. I guess CookieSerializeOptions was renamed to SerializeOptions?

Describe alternatives you've considered
Sticking with 0.7.2 but that's hardly a long term solution.

Additional context
I recon this is pretty straight forward.

I encountered this error today after updating dependencies to resolve a security warning about cross-spawn. After the updates, engine.io was installing cookie 0.7.2, but another package installed cookie 1.x, and it seems TypeScript was expecting engine.io to reference types from cookie 1.x.

For now I was able to solve this by pinning the cookie package to the 0.7.2 version with the following addition to my package.json:

  "overrides": {
    "cookie": "0.7.2"
  },

Thanks for the heads-up 👍

That's a bit weird, since we're using @types/cookie@^0.4.1. Not sure why the CookieSerializeOptions type is not found.

That being said, I think we will simply upgrade to cookie@1, since there seem to be no breaking changes for our usage: 7427109

A quick note here: I encountered this issue, because I had installed 'fastify', which some where in the dependency tree had a dependency to "cookie": "^1.0.1". Luckily I can get by without using fastify for now, but I will look forward to a upcoming release of socket.io, that depends on cookie@1.
