Let's figure out how to make this easier to use.

I think the following things would make this a lot easier for consumers to install and use:

- Pre-built binaries for all platforms shipped with the package on NPM
If we do this we can remove bsb-native, right @jaredly? I remember you mentioning something about azure pipelines to make the pre-building happen.

- A less complex name for the PPX flag.
I need to dig into why the name for the PPX flag is so funky right now. It'd be really nice to tell users in the readme that they can just add `let-anything` to the PPX flags, instead of `let-anything/lib/bs/native/let_anything.native`. But maybe it's unavoidable? Would Bucklescript have to understand more about NPM structure to allow using something so simple as the PPX flag?

Start by reviewing the NPM packaging setup, bsb-native, the Azure pipelines reference, the PPX flag usage, and the README guidance mentioned in the issue. Define the supported platforms and the desired package and flag experience first; the work is done when those decisions are implemented and installation and PPX configuration are simpler for consumers.
