Upgrade dependencies to fix npm audit

What's Changed

• Minor dependencies upgrade by @Xvier in #24

Full Changelog: 1.2.1...1.2.2

Lesser update

Updated the dependencies to the latest version.

Replaced Request

The nodejs Request package is deprecated. So with the help of @morficus we changed the
existing code to use cross-fetch.

On the usage part nothing is changed, only the node package request is changed to cross-fetch.

User Agent

Its now possible to add a useragent string to the request.

Fixed Cannot find module

Released new version with minor bug fix.
The file downloadFileCommand was in PascalCase and this was not supposed to be.
