Node.js 10 is about to reach EOL so we can drop CLI support in the next major release. We'll support 12+ going forward.
Node.js 12 needs `es2019` because it doesn't support the `es2020` features of optional chaining and nullish coalescing as seen from the [compatibility table](https://kangax.github.io/compat-table/es2016plus/#node12_11).
This PR fixes an error that happens when `includeFiles` has `.ts` files:
```
ReferenceError: Cannot access 'tsCompile' before initialization
```
~~However its not clear what the expected behavior is. Should the `.ts` files be compiled to `.js` or should they be considered assets and included as-is?~~
We will assume that `includeFiles` is only for assets and thus `.ts` files should not be compiled, they're included as-is.
