Subject: [PATCH] fix: respect `inputSourceMap` loader option

Currently, when the loader is invoked without a `map` object the `inputSourceMap` fallbacks to `undefined`.

This caused the sourcemap to be loaded by Babel since this defaults to `true` https://babeljs.io/docs/en/options#inputsourcemap

Thus, currently there is no way to disable `inputSourceMap` when using this loader.
