Hive: Provide a method of updating the `homePath`

[MichaelM97]

Is your feature request related to a problem? Please describe.
In my app, I initialise Hive when a users logs in passing their user ID as the subDir where all Boxes should be stored. If a user logs out then logs back in (either as themselves or as a different user) I am unable to re-initialise Hive using the new ID as HiveImpl#init performs the following check

if (homePath != null) {
    throw HiveError('Instance has already been initialized.');
}

Describe the solution you'd like
Perhaps a new method like Hive.updateHomePath(String newSubDir)? Or Hive.reinitialize(String subDir)?

Describe alternatives you've considered
For now I will need to manually add the users ID to the begining of every box path.

I'd also like the feature to reinitialize Hive with a different path. I use Hive for caching and would like to be able to switch at runtime between a locally running server and a staging server.

Would a PR be accepted?

In Hive 1.* I could call Hive.init() multiple times and it worked:
See: #595

Hey @leisim , can you look at the issue? I think we have to allow changing homePath's value multiple times to not break exists use cases.

On latest version Hive now supports calling .init multiple times to update homePath
