ESlint does not behave correctly when importing `fetch-charset-detection`

[martinratinaud]

Hi all,

While using fetch-charset-detection on the Open Terms Archive, importing of this library is causing an eslint error with

error  Unable to resolve path to module 'fetch-charset-detection'  import/no-unresolved

I made a reproducable environment which behaves with the same error

This does not happen with other packages.

It might because there is no main in the package.json
