Missing sourceMap

[Johannes Maron]

Hi there 👋,

Thanks for maintaining this wonderful open-source package ❤️

While adopting to ESM, I noticed a missing sourceMap:
wasm-imagemagick/dist/bundles/magickApi.js points to a sourceMap wasm-imagemagick/dist/bundles/wasm-imagemagick.esm-es6.js.map which does not exist.

I hope this information helps. Please let me know if you can contribute anything.

Best!
Joe
