when using experimental loader flag, issue with longFormatter being exported twice

[tomalaforge]

longFormatter is being exported twice. Inside format file and inside the parse file.

Do we really need to export it twice?

When using the flag --experimental-loader, we have the following issue:

file:///xxx/node_modules/date-fns/index.mjs?iitm=true:1714
    let $longFormatters = $1713274025149ebd0a3f5.longFormatters
        ^

SyntaxError: Identifier '$longFormatters' has already been declared

Hmm I agree this is a problem because of the re-exports in the root barrel file.

I wonder if this is contributing to the Parcel tree-shaking issues in #3744 and #3670 as well.
