Allow to pass object to fromJSON

Use case scenario:

Server renders:

<script>
window.__PRELOADED_STATE__ = ${transit.toJSON(preloadedState)};
</script>

Client picks up __PRELOADED_STATE__, which is a valid JSON, therefore it is converted to an object. To use it, I need to cast it back to string, e.g.

console.log('window.__PRELOADED_STATE__', transit.fromJSON(JSON.stringify(window.__PRELOADED_STATE__)));

Alternatively, I can stringify the object twice on server: once using transit-immutable-js and second time using JSON.stringify, e.g.

<script>
window.__PRELOADED_STATE__ = ${JSON.stringify(transit.toJSON(preloadedState))};
</script>

Preferably though,transit-immutable-js should be able to accept an object.

I don’t think it’d be that difficult to create a transit.decoder instance and accept an object without the additional stringify - this issue isn’t currently affecting me so it’s not high up my list of things to do, but I’d definitely take a PR (and help with landing it).

If it does cross my path requirement-wise in the near future I’ll probably tackle it myself.

Sorry, I don’t have time to make contributions to new OS projects. Have my hands full.

No worries, I know the feeling!
