Other improvements:
- Makes the pcbData parameter in DetourFindPayload and DetourFindPayloadEx optional, so that if an application only needs to search for the presence of a payload, they can ignore the size by passing nullptr.
- Makes the pvData parameter in DetourCopyPayloadToProcess const, so that a pointer to a const C++ object can be passed instead of the object needing to be const_casted or being non-const.
- Adds DetourCopyPayloadToProcessEx, which has the same interface than DetourCopyPayloadToProcess, but it returns the address of the payload in the remote module, if the program later wants to write to it.
- Add payload example and extra unit tests covering new APIs.
