[FR] Can this plugin be made into a UPM Package?

* Can this plugin be made into a UPM Package?

Makes it easy to update the package via Unity Package Manager, as in the current plugin I had the version 1.2.171, the settings > Update button did nothing in the plugin.

Also this would help with ease of install on the Github Readme for this plugin, currently the Readme doesn't have a simple and easy to find recommendation of how to install the plugin - most of the time when I am on github looking for Unity packages, I would expect to see a very simple 'How to Install' or 'Quick Start' at the top with a git url to paste into package manager + also a link for the actual package file too - see this example https://github.com/Elringus/UnityGoogleDrive#installation
