Describe the PR
Adds a seed corpus for the fuzzer based on real USB packets captured using wireshark.
Additional context
By default, a fuzzer will try to randomly search for inputs that increase code coverage. In some cases this can take a really long time for the fuzzer to "learn" the structure of a protocol. One approach to mitigate this problem is to give the fuzzer a good starting point, with valid inputs. To do this I've captured a bunch of USB packets using wireshark. To make adding to this corpus easier I've added a tool to parse wireshark captures and add them to the zip corpus.
