Consider turning on stricter typescript options

[charlespwd]

Is your feature request related to a problem? Please describe.

We keep committing unused variables, unused imports, etc. It's not great for code quality over time.

{
    // "strictNullChecks": true,                         /* When type checking, take into account 'null' and 'undefined'. */
    // "strictFunctionTypes": true,                      /* When assigning functions, check to ensure parameters and the return values are subtype-compatible. */
    // "strictBindCallApply": true,                      /* Check that the arguments for 'bind', 'call', and 'apply' methods match the original function. */
    // "strictPropertyInitialization": true,             /* Check for class properties that are declared but not set in the constructor. */
    // "noImplicitThis": true,                           /* Enable error reporting when 'this' is given the type 'any'. */
    // "useUnknownInCatchVariables": true,               /* Default catch clause variables as 'unknown' instead of 'any'. */
    // "alwaysStrict": true,                             /* Ensure 'use strict' is always emitted. */
    "noUnusedLocals": true,                           /* Enable error reporting when local variables aren't read. */
    "noUnusedParameters": true,                       /* Raise an error when a function parameter isn't read. */
}

Describe the solution you'd like

I would like to consider some of the stricter TS compiler options and implement them. I would also like this to not prevent fast prototyping. If you press F5 and have unused variables, that should be totally fine (?)

It's a fine line to navigate because that also means that you might only fail in CI and not locally.....
