Expose RawTable publically

[hansihe]

I find myself in the need of writing a hash map with some custom ownership semantics in regards to keys.

Your internal RawTable seems to provide exactly the functionality I, with enough flexibility to provide the custom semantics I need.

Would you be open to exposing RawTable publically, possibly behind a feature flag? I do realize that the API most likely is very unstable and may change, but this is something I would be willing to deal with.

Could you give a bit more detail regarding the ownership semantics for your hash map?

I'm somewhat open to the idea, but the current RawTable API isn't very user-friendly.

I would also like it, to have direct (unsafe) access to the entries by index.
The objective would be to replace the current IndexMap used inside my PriorityQueue and remove one level of indirection that I don't need.
