This is technically a breaking change, but: a) We need the end handle to do descriptor discovery properly. b) We have no possible use for the existing definition handle in the characteristic result IRQ. None of the methods can use it, and therefore no existing code should be using it in a way that changing it to a different integer value should break. Unfortunately NimBLE doesn't make it easy to get the end handle, so also implement a mechanism to use the following characteristic to calculate the previous characteristic's end handle.
