Replace homepage

[neocotic]

Currently, there's still some references to my homepage (https://neocotic.com/qrious). I would like to get rid of these references and create a new homepage just for QRious. It will be hosted on GitHub Pages (e.g. https://neocotic.github.io/qrious), but I'll need to make some changes to my own homepage first before I can do this (otherwise it will keep automatically redirecting to https://neocotic.com/qrious).

If it gets traffic, I'll consider paying for a custom domain, but not until then as I've made that mistake before 💸.

The new homepage should be clean and informative, making usage documentation and a live demo the primary content. Once it's up and running, all references to a "homepage" should be changed to point at it.

All references on qrious-core and node-qrious should also be updated.
