Fix vulns and allow react 17.0.1

[BryanDollery]

Hey,

I have to use this with react 17.0.1. I have also found that dayjs reports 2 vulnerabilities.

So, I have forked your repo and fixed the problems (upgrade branch) and all the tests still pass (at least, I didn't break any more -- the linter is complaining about state hoisting). It's easy enough for you to fix yourself, or I could issue a pull request if you like.

Hi @BryanDollery,

Thanks for doing this! Can you give release 0.3.2 a try?

Thanks!
