Subject: [PATCH 3/3] test: test imports with npm package contents

Especially for publishing CommonJS/ESM/Browser dual packages a lot can
go wrong in the actual build and release step, see:
https://medium.com/javascript-in-plain-english/is-promise-post-mortem-cab807f18dcc

In order to catch regressions with respect to the supported ways of
importing this library it makes sense to test this using `npm pack`.

Fixes #424
