Improve tree shaking?

Hi there,

I was interested in using longfn to reduce bundle size a little bit compared with long.. I thought the 'pure function' way that longfn works might lend itself to tree shaking but the bundle was maybe not 'tree shaken'.

I probably obsess over bundle size too much but it is including the entirety of longfn (6kb minified) instead of just the functions imported. (for comparison long.js ~10kb minified)

A production build using vite with just longfn imported can show this


Screenshot above made using "yarn build" in the repro, then running server in dist, and running "npx bundle-wizard http://localhost:3000"...of course react the major culprit in bundle there
