Fix TypeScript issues

Commander can automatically import files for us by specifying
'executableFile' for commands. This unfortunately doesn't work well with
TypeScript, which was why we were using `node -r ts-node` to run the CLI
instead of `ts-node`. This setup to get commander working was also
causing other issues with file imports.

This commit updates so we now manually import files for commands, which
enables us to revert the less-conventional TypeScript config.
