Decrease first load JS size shared by all

[btalb]

Currently it is heavier than it should be (~223kB).

Here's a sample output:

ben@ben-meshify:~/qut/repos/qcr.github.io$ npm run build

> [email protected] build
> npm run build_loaders && next build


> [email protected] build_loaders
> npx tsc -p lib/loaders/

○  (Static)  automatically rendered as static HTML (uses no initial props)
●  (SSG)     automatically generated as static HTML + JSON (uses getStaticProps)

Need to look at bringing this down (use @next/bundle-analyzer and have a look at the client bundle HTML).
