TypeScript house cleaning

[pschroen]

Finished going through all 46 examples (48 if you include the readme examples), I've made a number of updates, most of which are just consistent spacing and indentation, though there are some updates like the removal of unnecessary return await.

All of the code has been run through prettier and verified to be working. 😉

Process while working on the OGL typings:

1. Copy-pasted all 48 examples (including readme examples) into my OGL Vanilla TypeScript Template while working on the definitions.
2. Resolved all build errors and added definitions where needed.
3. Updated all source files with any discrepancies found.
4. Copy-pasted all the TypeScript versions of the examples back to the source files, removing the type annotations.
5. Formatted all files with the OGL prettier config.
6. Re-tested all the examples.

Next step is cleaning-up my working copy of all the definitions.
