sourcemap-codec

* Use Uint16Array to prevent overflow ([#75](https://github.com/Rich-Harris/sourcemap-codec/pull/75))

* GO EVEN FASTER ([#74](https://github.com/Rich-Harris/sourcemap-codec/pull/74))

* GO FASTER ([#71](https://github.com/Rich-Harris/sourcemap-codec/pull/71))

* Add TypeScript declarations ([#70](https://github.com/Rich-Harris/sourcemap-codec/pull/70))

* Update build process, expose `pkg.module`

* Fix bug with lines containing single-character segments
