fix: remoteLoader pure functional on browser env

[semoal]

Fine tunning of #1080, now we release a new package @lingui/remote-loader, instead of using the @lingui/loader.

Loader dependencies are so much oriented to node environments, for a safer usage and extendability I decided to extract the remoteLoader to a new package with esm, and cjs exports usable on node and browser.

Pending to add documentatio to this new tool, the API it's simple:

remoteLoader({ messages, fallbackMessages?, format: 'minimal' }}
