feat: improve tree shaking support

[deodad]

What is the feature you would like to implement?
Structure our package distributions to better support tree shaking by not bundling into a single index file.

Additional context
The safest form of tree shaking relies on ES module structure to eliminate unused code. We currently bundle our package distributions into a single index file, which makes this kind of tree shaking impossible.

I'd suggest just transpiling with tsc. This would also make #411 viable.

Is this assigned yet? Happy to take a look.

It is not, thank you!

Wondering if it would be as simple as adding treeshake option to tsup in places like here: https://github.com/farcasterxyz/hub-monorepo/blob/main/packages/core/tsup.config.ts

Since we are building a library, we aren't bundling our dependencies which is where tree shaking would happen. Instead we want to make our library more tree shakable for end consumers by not combining the modules into a single file.

Great right up here https://cmdcolin.github.io/posts/2022-05-27-youmaynotneedabundler
