Fixing a regression spotted in pnpm: pnpm/pnpm#1905

The port in the Node.js URL object is a string, so it is more convenient to
use string for the port.

* Use an `EventEmitter` to replay failed proxy connect HTTP requests

This is a fix for https://hackerone.com/reports/541502.

Aborts the upstream proxy connection and instead uses a vanilla
`EventEmitter` instance to replay the "data" events on to. This way,
the node core `http` Client doesn't attempt to write the HTTP request
that is intended to go to the destination server to the proxy server.

Closes #76.
