fix: Use subpath imports to choose Node or vanilla JS environment

[ukstv]

The changes here address #87

Note FYI: There is no indication of a package manager used. If using PNPM, which is slightly more strict than NPM, some of the transitive dependencies from aegir like @types/mocha, @types/node, mocha are considered to be unavailable. The PR has no related changes.

FYI @achingbrain we've seen this come up a few more times with Ceramic users, would be great to get this in if possible.

@ukstv I've made a couple of changes:

1. Import { Buffer } from node:buffer to make it easier for bundlers to polyfill if necessary (no need to mutate the global object)
2. Add React Native overrides in package.json. It turns out React Native supports the exports map but not the imports one

Can you take a look at the updates please?

I'm pretty sure it's related, but since this got merged, I've been having problems using packages that depend on this package in Codesandbox with Parcel. example

The error I get:

Could not find module in path: 'uint8arrays/dist/src/util/#alloc' relative to '/node_modules/uint8arrays/dist/src/util/bases.js'

I suppose this is bundler dependent and I haven't tried to debug this too much, so any pointers would be helpful.

[ukstv]

@2color Indeed, this is bundler-dependent. Parcel AFAIK still relies on explicit opt-in to enable subpath imports/exports. parcel-bundler/parcel#7840 (comment) and https://parceljs.org/features/dependency-resolution/#package-exports tell if you add

 "@parcel/resolver-default": {
    "packageExports": true
  }

to package.json, that should enable subpath imports/exports.
