Add tcpdump to Npcap installer #1341
The main Windows tcpdump port is currently windump.exe by the WinPcap folks. But like winpcap, it hasn't been updated in years and isn't really maintained. It also doesn't work with our Npcap because it relies on a too-old libpcap. But the changes to make current tcpdump work on Windows with Npcap are minor (we've done it in initial testing) and a lot of us still love tcpdump (even though it doesn't hold a candle to the amazing Wireshark feature-wise).
So the thought is that we should probably make a tcpdump.exe that uses Npcap (submitting any needed changes upstream for hopeful incorporation) and then we could include that as an optional (install by default) checkbox component. It would be useful both to everyone who appreciates tcpdump for Windows, and also handy as a quick check that an Npcap install is working. The tcpdump builds we have been making are less than 1mb, so fairly immaterial space wise. And of course people can choose not to include it in the install by unchecking or using command line installer option if desired.
