build(rollup): upgrade rollup, consolidate config, remove cross-env

 rollup  ^1.26.3  →  ^1.32.1

Consolidate `build:min` and `build:unmin` into 1 `build` script.

Remove `cross-env` since NODE_ENV is no longer needed to
distinguish between builds.

In `rollup.config.js`, export both configs for minified and
unminified bundles.

Generate sourcemap for both builds (previously, sourcemap was
only generated for unmin or development bundle).
