Feature idea/request: Option to kill the ancestor's process tree

[ProvokerDave]

Killing a dotnet watch or nodemon process tree that hosts a listen port is never fun, but kill-port could actually make it fun!

My thought is kill-port could have an option to find the parent process of the process that is listening on the port and then kill the parent process' tree. Also, I can imagine, given how intermediate launch shell or node processes could be between the daemon watcher and the listening process, there should be a setting to indicate how many levels of ancestors to traverse up before doing the tree kill with the default being 1. So, something like:

kill-port --port 5000 --parent     # kills the parent process tree of the process listening on port 5000
kill-port --port 3000 --ancestor 3 # kills the great-grandparent process tree of the process listening on port 3000
