potgo.resource jump table

potgo.resource's calls, as OpenPotgo builds them: LVO, call, registers, and after the # the call's core class (OPEN_LIBRARIES.md section 5). build-amiga.sh (with ../../libraries/common/check_fd.py) checks this against the NDK 3.2 potgo_lib.fd (##bias 6) in the stove and stops on any difference; openpotgo_res.c's res_vectors[] follows it line for line. A resource has no Open, Close, Expunge or Null: its calls start at -6.
