Fixed reserveWithTimeout & made connect options optional

[only-cliches]

According the README connect options are optional:

await beanstalkd.connect() // Connects to localhost:11300
await beanstalkd.connect({ host, port })

The current typescript definitions require the connect options:

This pull request makes the connect options optional.

reserveWithTimeout command was not working as expected, it would hang indefinitely when I tested it.

The additions to the PR fix the behavior of reserveWithTimeout to make it return an error on timeout and a job on success and also adds reserveWithTimeout to the typescript definition file.

Hello @ClickSimply! So it looks like you're solving two separate issues in one PR.

I would recommend opening a separate pull request for the Typescript fix given that it's purely semantic in nature, and having this pull request deal only with reserveWithTimeout. That way I can review reserveWithTimeout on its own.

Also, it looks like you'll need to fix your author email on your Git commits.

Thanks for your help with jackd!
