Current Behavior

TSDX doesn't seem to have the expected output when building a package with a default export. The type definitions are output as expected, but the resulting .js file actually exports as { default: /* value */ }. I've created a minimal, reproducible example at rtbenfield/tsdx-default-export bootstrapped from tsdx create. This is my first time using TSDX and it is possible I am just doing something incorrectly.

In the repo mentioned above, I changed the sum function to be a default export, then added output.test.ts which imports directly from dist instead of src. output.test.ts logs the value of import sum from "../dist" and is showing sum to be { default: ... } instead of the actual function.

Expected behavior

The .js output files in dist can be consumed as default exports (ex. import sum from "my-module") if the source file utilized default exports.

Suggested solution(s)

Unsure, but willing to investigate if this is confirmed to be an issue. I know Webpack, but not Rollup, so it could be a good excuse for me to get some experience with it.

Additional context

Nothing relevant that I know of.
