Fix lint errors and update package-lock.json

This commit fixes lint errors and updates package-lock.json /
package.json.

package-lock.json / package were generated by reverting:
git checkout 5ce291934eba5a2d114b756f33ff62f9ac0db632 -- \
    package-lock.json package.json

... then running ...

npm install yargs

Note: timezone-boundary-builder ran without adding yargs explicitly
because it is a transitive dependency of some other packages already
used, but recording the dependency seems like good practice.

"npm audit fix" was _not_ run.

Tested with:
$ node --max-old-space-size=8192 index.js \
    --downloads_dir=mydownloads \
    --dist_dir=mydist \
    --included_zones America/New_York America/Chicago
