Fix String.fromCodePoint.apply in ts and fix outdated .js

- The call to `String.fromCodePoint.apply` was erroring because `CallableFunction.apply`
expects a strict Array, but we're passing a Uint8Array, which is just ArrayLike
- The .js file was outdated, causing the previous version to not have had any  impact
whatsoever, so run `tsc` to fix it and apply the latest changes. This means that the
minor version of the package had to be bumped as well
