Add hook for modifying initialState

[kirkobyte]

It would be great to add a hook that allows modifying initialState within a plugin.

For example, I've been wanting to build a useQueryStringTableState plugin which will store the table's state in the query string and restore table state from the query string on reload. The intention of this being to enable sharing/bookmarking links with certain sorting etc.

Writing a plugin using the stateReducer hook doesn't work well. Once data is loaded, all of the reset* methods will be called to reset each value. But disabling the auto reset options isn't ideal for when the data changes in a more tangible way (e.g. filtering options changing).

For the time being I've worked around this by writing a plugin to store the data, and a separate React Hook to retrieve the items like so:

useTable({
  initialState: useStatefulInitialState({
    queryParameterKey: 'tablestate'
  }),
  useQueryStringTableState
});

But that requires a separate hook and the user to be using both the hook & plugin correctly
