Allow updating the guesses grid

[hubgit]

Apologies if this already exists and I've missed it, but could there be a way to update the guesses grid (perhaps via a ref prop) after the component has initialised?

This would allow the guesses state to be stored remotely and updated by collaborators.

Hi @hubgit - you can use the saveGrid prop to override the default localStorage solution i.e. it runs when the guess grid changes, but there isn't currently a way to programmatically update it ad hoc. PRs are very much welcome for this!
