hashbang binary configuration

[souporserious]

First, thank you for this project! It's such a simple, but powerful build tool ❤

I was curious if you've thought about using the presence of the hashbang (e.g. #!/usr/bin/env node) in a file to automatically infer binary configuration? It would be nice to not need a directory as part of the binary configuration and could lean into being a little less config or having to look up docs for it.

Hi thanks for the feedback! The preseving of shebang #!/usr/bin/env node already works with bunchee. But for exposed commands in ./node_modules/<your lib>/<binary cmd>, you still needs to define it in "bin" field to configure it hence I add the convention bin folder to match the configuration in package.json.

I like the idea that we probably don't need the folder as it's almost same, will think about improvng that in the future release 🙌
