Old deprecated dependencies

Hi,

Once I've installed `confluentinc/kafka-javascript`, I'm greeted with the following warnings:

```
npm warn deprecated inflight@1.0.6: This module is not supported, and leaks memory. Do not use it. Check out lru-cache if you want a good and tested way to coalesce async requests by a key value, which is much more comprehensive and powerful.
npm warn deprecated rimraf@3.0.2: Rimraf versions prior to v4 are no longer supported
npm warn deprecated glob@7.2.3: Glob versions prior to v9 are no longer supported
npm warn deprecated are-we-there-yet@2.0.0: This package is no longer supported.
npm warn deprecated gauge@3.0.2: This package is no longer supported.
npm warn deprecated npmlog@5.0.1: This package is no longer supported.
```

The first one seems not good at all. Is there a plan to upgrade the dependencies? I've installed the version 1.2.0 of `confluentinc/kafka-javascript`.

Cheers!
