The reason I made those patches was because of this rollup error I got multiple time while trying to build
```Found debian/nodejs/./build
cd ./. && sh -ex debian/nodejs/./build

This is the line that clearly shows it was not exported as default in fetch-blob/file.js
There were abou three more occurrences like this that I had to correct. Is there a better fix for this?
