Update dependencies

[Justus-at-Tazama]

As a Tazama operator,
I want the dependencies for each repository to be up to date, lean and focused,
So that the latest identified vulnerabilities have been addressed,
And so that there are no unnecessary dependencies that could increase the API surface area for vulnerabilities unnecessarily,
And so that transpiled modules are as small as possible

Acceptance Criteria

1. Remove unnecessary, unused or redundant modules from package.json (consider installing and running npm-check)
2. Run npm update to update the listed dependencies to the latest versions
3. Resolve any missing or broken dependencies
4. Run npm i and ensure no errors
