Security and deprecation warnings, dependencies update is required

When installing this package I get the following warnings:
```console
npm i -D dependency-version-badge
npm warn deprecated debug@4.1.1: Debug versions >=3.2.0 <3.2.7 || >=4 <4.3.1 have a low-severity ReDos regression when used in a Node.js environment. It is recommended you upgrade to 3.2.7 or 4.3.1. (https://github.com/visionmedia/debug/issues/797)
npm warn deprecated async-cache@1.1.0: No longer maintained. Use [lru-cache](http://npm.im/lru-cache) version 7.6 or higher, and provide an asynchronous `fetchMethod` option.
```

Start by inspecting the package dependency manifests and reproducing the npm install output for debug and async-cache. Done means the dependency versions no longer produce the reported deprecation or security warnings during installation.
