editcap: add change offset.
This option skips some bytes when fuzzing, that prevents some headers from being changed. This focuses fuzzer to a smaller part of the packet.

+When used in conjuction with -E, skip some bytes from the beginning of the packet
+from being changed. In this way some headers don't get changed, and the fuzzer is
+more focused on a smaller part of the packet. Keeping a part of the packet fixed
+the same dissector is triggered, that make the fuzzing more precise.
