Multiprocess support - missing Readme.md info

[cj-marius-duna]

I don’t see anything in the Readme.md about whether the library works with multiple processes in the same application.

Is that supported?

I guess it is a good starting point to migrate from SharedPreferences to Multiprocess Data Store
