debugpy may not free port

[ioncodes]

If specific (and currently unknown) conditions are met, debugpy may not be able to kill the spawned Python process (debug server). A possible solution would be to hook the process creation function, make a copy of the process ID and then force kill it once IDA closes. This is a very hacky solution but it seems like debugpy doesn't provide specific API to tear down the debug server.

This issue was created in reference to #11.
