This PR introduces a new NonFungibleAdapter.

It will be useful for enabling cross-chain Coretime region transfers, as the existing NonFungiblesAdapter is unsuitable for this purpose. This is due to the fact that there is only one class of items within the pallet-broker, i.e., the Coretime regions.

@joepetrowski Could you take a look at this?

Yeah I can review, but if it's for Coretime then I think @seadanda knows this better.

Looks good, just needs an update to XCM v4 syntax.

Perhaps these should be proper log messages and not debug_asserts. You are assuming that the user has e.g. called can_check_in prior to calling this function, but there is no guarantee. If the trait doesn't allow you to return an error here, should probably log it.

I used debug_assert here to keep consistent with other adapter implementations.
