I saw this issue in a recent pull request, and I believe It's happening because of using module.exports then trying to import using ES6 syntax in Tag.js. To fix this issue, I believe we can change the export style in dicom.js to ES6.
I did this and I tried running the build command, I didn't get any errors from rollup.
