Replace Moment.js with a lighter-weight alternative

[outoftime]

Moment.js contributes a disproportionately large proportion of our bundle size given its limited actual use in the application. dayjs is an API-compatible replacement that is much smaller, though we would have to confirm it supports the browsers/versions we need. date-fns is another library that, while not API-compatible, has been much-touted recently as a good replacement for Moment.

To evaluate effectiveness at reducing bundle size, you can build a production-like environment with:

$ PROFILE_BUILD=true npm run preview

And then access:

Happy to take this on!

Currently we're using Chrono which itself depends on momentjs. However they plan to switch to dayjs. Once that is done, Popcode can upgrade chrono, switch to dayjs and reap the benefits.

See wanasit/chrono#285

I have a local Chrono branch where I've started the porting process. We'll see whether I finish my branch or they update it themselves first.
