Replace jsdom and d3 libraries with leaner libraries such as cheeriojs

[orbitalsqwib]

Currently, the jsdom and d3 libraries have been imported to generate HTML for the QRCodeService module.

However, we only use a small subset of the functionalities contained within these libraries.

As such, we could look into alternative replacements to reduce the memory footprint of the client app and decrease loading times.

One suggestion is cheeriojs, a Javascript library that can parse, traverse and manipulate HTML, but does not implement features such as visual rendering, applying CSS, loading external resources, or executing JavaScript. I think it's a close match for our needs.

Metrics that can be used to measure the effectiveness of this proposal include the client app load time as well as the time taken to generate QR Codes.
