Add MemoryPreference artifact?

[NightlyNexus]

I have rewritten MemoryPreference a few times in various projects for tests and mock mode.

public final class MemoryPreference<T> implements Preference<T> {
  private final String key;
  private final T defaultValue;
  @Nullable private volatile T value;
  ...
}

Maybe there should be an artifact here for it?

Is there a strong reason to prefer a memory backed preference over just a normal preference?

Actually, I guess it might make sense if you're not using Robolectric.

[NightlyNexus]

Yes, I don't use Robolectric.

@NightlyNexus show full code, please =)

Is this still on the table? I basically have a small test class that i end up copying in every project I use this library in. Would be nice to have an official artifact. Happy to contribute a PR or continue on the existing one
