Analyse and optimise dependencies and polyfills

[aurelticot]

Check the following:

• Upgrade dependencies
• Remove unused dependencies
• Check polyfills are actually needed (see in config-overrides.js), try disabling them
• Check @verida/* deps for optimisations
  • For tree-shaking, use named export instead of default
  • For tree-shaking, use named import instead of global
    • Example lodash is often fully imported in a file but only the function merge is used
  • Challenge having classes
  • Try pure functions instead of static methods in a class
