new packages list:

• BabylonReactNative-Base
• BabylonReactNative-Windows (?)
• BabylonReactNative-Camera
• BabylonReactNative-XR

Shall we do the separation between ios/Android and Windows?

Current state of investigations.
It's possible with a GitHbu action to upload artifacts to a release.
When doing a new Tag/Release, this action is kicked : https://github.com/BabylonJS/BabylonReactNative/blob/master/.github/workflows/publish.yml
It builds, generate artifacts per platform/RN version. Each artifact is then published to npm (to make it quick)

A prototype to also add these artifact to the github release is visible here : https://github.com/CedricGuillemet/BabylonReactNative-1/blob/master/.github/workflows/append_release.yml

Result is a release with each platform/RN version artifact available to download.

At installation time, the front end NPM will download the tgz corresponding to its version.
The same way as node-sass does ( https://github.com/sass/node-sass/blob/master/scripts/install.js ) or puppeteer (https://github.com/puppeteer/puppeteer/blob/main/packages/browsers/src/install.ts#L103 )

2 things to note:
Because of constraint environments, these packages allows to have different sources that can be overriden by an env var:
https://github.com/sass/node-sass/blob/87f38998da059d13a87a7fc9f3d29d5728128e2c/lib/extensions.js#L247
Cache is handled by the installation code like this:
https://github.com/sass/node-sass/blob/87f38998da059d13a87a7fc9f3d29d5728128e2c/scripts/install.js#L68

These 2 mecanisms can be added to the BRN front end plugin.

I did a sucessful test using NPM package download instead of GitHub Assets that might be easier to deploy in some environments. What ever is the tech behind this front-end package, it must supports these features:

• npm install react-native@latest must trigger an update (works with postinstall)
• Supports mirroring of npmjs (suitable for npm packages, not for Github assets)
