Do not keep process alive waiting for request timeout

[terotil]

When using rate limiter with node CLI script, it unnecessarily keeps node process alive waiting for request counter timeout. Using unref() is an uncompromising way of letting the process exit if all else has been executed except the request counter timeout.

BTW Linter doesn't pass with clean clone from current master (with or without my change). It complains

 Error: /home/tero/src/axios-rate-limit/node_modules/@logux/eslint-config/base.js:
	Configuration for rule "import-helpers/order-imports" is invalid:
	Value {"groups":[["absolute","module"],["parent","sibling","index"]],"newlinesBetween":"always"} should NOT have additional properties.

I didn't try to fix that.

Apparently the linter failure was caused by me using npm instead of yarn and therefore dependency locking was not obeyed. With yarn it is working.

Thanks for the fix!

I just published version 1.1.2.

@terotil Could you test version 1.1.3 and reply how it works please? I've recently updated ref-related behaviour because of #16

A little late to the game... but working nicely still.
