Include sourcemaps in npm tarballs

Sourcemaps are not currently published to npm due to the omission of
`*.map` under `"files"` in `package.json`. This leads to many downstream
challenges with editors and developers tools that expect these files
(since they are linked to the source `.d.ts` and `.js` files).
